tests/tcg/multiarch: don't hard code paths/ports for linux-test

Browse source 
The fixed path and ports get in the way of running our tests and
builds in parallel. Instead of using TESTPATH we use mkdtemp() and
instead of a fixed port we allow the kernel to assign one and query it
afterwards.

Ideally test directory creation should be common functionally across
all TCG tests but this could complicate an already huge patch series
so we mark it as a TODO for next time.
