[0/3] Fix various bash constructs in tests

Message

These tests were either failing or printing warnings on my Ubuntu 18
and 20 systems. I'm not sure if there is a system where /bin/sh allows
bash constructs, or perf invokes bash instead of sh, but I saw that
there have been similar fixes made in the past so I assume this should
be done.

Adding set -e to the scripts didn't highlight these issues, so I didn't
do it at this time.

For stat_bpf_counters.sh, there are further bashisms after the skip,
but I couldn't get BPF working, so I only fixed it up to that point.

Applies to perf/core 624ff63abfd36
