Subject: [PATCH] perf test trace_btf_enum: Fix shellcheck warning

Shellcheck versions < v0.7.2 can't follow this path so add the helper to
fix the following warning:

  In tests/shell/trace_btf_enum.sh line 13:
  . "$(dirname $0)"/lib/probe.sh
  ^--------------------------^ SC1090: Can't follow non-constant source.
  Use a directive to specify location.

Fixes: d66763fed30f ("perf test trace_btf_enum: Add regression test for the BTF augmentation of enums in 'perf trace'")
