[Buildroot] [git commit] support/tests: use relative test_dir

[Thomas Petazzoni]

commit: https://git.buildroot.net/buildroot/commit/?id=ebe61135c9a242ac39204cbd901fa9f407dae069
branch: https://git.buildroot.net/buildroot/commit/?id=refs/heads/master

When we list the available tests, we use test_dir, which is set from
the path of the script. However, when we run the tests, we use the
hard-coded path.

Ditto to find the config file.

For consistency, always use test_dir.
