[Buildroot] [PATCH 04/16] utils/checkpackagelib: instruct shellcheck to follow included files

[Yann E. MORIN]

We do have a few shell scripts that have source directives (either with
'source' or with '.'), and they all are currently either globally
ignored in .checkpackageignore, or have shellcheck directives to ignore
the source statement (SC1090).

So, we can safely instruct shellcheck where to lookup for sourced files;
that does not trigger any new error.

This will alow fixing some shellcheck errors in later commits.
