systemtap-static-probes-in-ruby: Add assertion to check stap command.

Browse source 
The assertion is to detect a stap command error not depending on Ruby, and also
to make us report an error to the rpms/systemtap easier.

You can see the upstream systemtap routine builds when an error happens on
Fedora rawhide. There may be the same error on the latest build.
https://builder.sourceware.org/buildbot/#/builders/systemtap-fedrawhide-x86_64

For example, the assertion can catch the following stap command error.

```
$ tmt -c distro=fedora-rawhide run --all provision -h virtual -i fedora-rawhide tests -n '^/systemtap-static-probes-in-ruby$'
/var/tmp/tmt/run-014
...
total: 1 warn

$ echo $?
1

$ tmt run --id run-014 report -vvv
