docs/system/s390x/protvirt.rst: Format literals correctly

Browse source 
In rST markup, single backticks `like this` represent "interpreted
text", which can be handled as a bunch of different things if tagged
with a specific "role":
https://docutils.sourceforge.io/docs/ref/rst/restructuredtext.html#interpreted-text
(the most common one for us is "reference to a URL, which gets
hyperlinked").

The default "role" if none is specified is "title_reference",
intended for references to book or article titles, and it renders
into the HTML as <cite>...</cite> (usually comes out as italics).

To format a literal (generally rendered as fixed-width font),
double-backticks are required.

protvirt.rst consistently uses single backticks when double backticks
are required; correct it.

To run PVMs, a machine with the Protected Virtualization feature, as
indicated by the Ultravisor Call facility (stfle bit 158), is
required. The Ultravisor needs to be initialized at boot by setting
`prot_virt=1` on the host's kernel command line.

Running PVMs requires using the KVM hypervisor.
If those requirements are met, the capability `KVM_CAP_S390_PROTECTED`
