[PATCH 03/63] perf tests: Use shebangs in the shell scripts

From: Michael Petlan <mpetlan@redhat.com>

Since the first line was used as a test identification, it needs to be
skipped by shell_test__description() function now.

Further notes from Hendrik:

It might be worth to note that adding the shebang is necessary to spot
them as scripts.

Using /bin/sh looks fine to. Just briefly checked whether the scripts
contains some bash-specifics, which is not the case.
