[kvm-unit-tests PATCH v3 2/6] run scripts need consistent exit status

[Andrew Jones <drjones@redhat.com>]

When a script fails on something build related, e.g. ./configure
hasn't been run, or usage related, e.g. a bad parameter, then an
exit status of 1 makes sense, as no test was attempted. However,
if a test is attempted, then we now need to reserve an exit status
of 1 for QEMU failures. arch-run scripts and standalone generated
run scripts should always use 2, as it's assumed that attempting
to run those attempt to run the test.

(Additional cleanup; remove return values from a couple of
 "void" functions in scripts/mkstandalone)
