[PATCH 2/2] perf build: Follow sourced files when running shellcheck

[James Clark]

Shellcheck follows sourced scripts when -a is provided, but only when
that file is also provided on the command line along with the one being
checked. We only ever provide one file at a time to shellcheck, so -a
does nothing.

Improve coverage by following sources using the script's directory as
the base path.
