vhost-user-test: Fix 'make check' broken on glib < 2.26
After commit 89b516d8, some logics is turbid and
breaks 'make check' as below errors:
tests/vhost-user-test.c: In function '_cond_wait_until':
tests/vhost-user-test.c:154: error: 'G_TIME_SPAN_SECOND' undeclared (first use in this function)
tests/vhost-user-test.c:154: error: (Each undeclared identifier is reported only once
tests/vhost-user-test.c:154: error: for each function it appears in.)
tests/vhost-user-test.c: In function 'read_guest_mem':
tests/vhost-user-test.c:192: warning: implicit declaration of function 'g_get_monotonic_time'
tests/vhost-user-test.c:192: warning: nested extern declaration of 'g_get_monotonic_time'
tests/vhost-user-test.c:192: error: 'G_TIME_SPAN_SECOND' undeclared (first use in this function)
make: *** [tests/vhost-user-test.o] Error 1
First, vhost-usr-test.c rely on glib-compat.h because
of using G_TIME_SPAN_SECOND [glib < 2.26] and g_get_monotonic_time(),
but vhost-usr-test.c defined QEMU_GLIB_COMPAT_H, which make
glib-compat.h will not be included.
Second, if we remove QEMU_GLIB_COMPAT_H definability in
vhost-usr-test.c, then we will get below warnings:
tests/vhost-user-test.c: In function 'read_guest_mem':
tests/vhost-user-test.c:190: warning: passing argument 1 of 'g_mutex_lock' from incompatible pointer type
tests/vhost-user-test.c:234: warning: passing argument 1 of 'g_mutex_unlock' from incompatible pointer type
That's because glib-compat.h redefine the g_mutex_lock/unlock
function. Those functions' arguments is CompatGMutex/CompatGCond,
but vhost-user-test.c is using GMutex/GCond, which cause the type
is not consistent.
We can rerealize those functions of vhost-user-test.c,
which need a lots of patches. Let's simply address it, and
leave this file alone.

vhost-user-test: use correct ROM to speed up and avoid spurious failures
The mechanism to get the option ROM for virtio-net does not block the
PCI ROM from being loaded. Therefore, in vhost-user-test there are
two entries in the boot menu for the virtio-net card: one as an
embedded option ROM, one from the ROM BAR.
The embedded option ROM in vhost-user-test is the non-EFI-enabled,
while the ROM BAR has an EFI-enabled ROM. The two are compiled with
slightly different parameters, where only the old BIOS-only one doesn't
have a timeout for the "Press Ctrl-B" banner. When using a new
machine type, therefore, the vhost-user-test has to wait for the
EFI-enabled ROM's banner to go away. There are several ways to fix
this:
1) fix the ROMs to have the same configuration
2) add ",romfile=" to the -device line
3) remove --option-rom and add the ROM file name to the -device line
4) use an old machine type
This patch chooses 3. In addition, the file name was wrong because
qtest runs QEMU relative to the top build directory, not to the
x86_64-softmmu/ subdirectory, which is fixed too.
