[kvm-unit-tests PULL 06/11] common.bash: run `cmd` only if a test case was found

[Thomas Huth <thuth@redhat.com>]

From: Marc Hartmayer <mhartmay@linux.ibm.com>

It's only useful to run `cmd` in `for_each_unittest` if a test case
was found. This change allows us to remove the guards from the
functions `run_task` and `mkstandalone`.
