[kvm-unit-tests PATCH] scripts: Fix the check whether testname is in the only_tests list

[Thomas Huth <thuth@redhat.com>]

When you currently run

 ./run_tests.sh ioapic-split

the kvm-unit-tests run scripts do not only execute the "ioapic-split"
test, but also the "ioapic" test, which is quite surprising. This
happens because we use "grep -w" for checking whether a test should
be run or not - and "grep -w" does not consider the "-" character as
part of a word.

To fix the issue, convert the dash into an underscore character before
running "grep -w".
