[PATCH nft v3 06/11] tests/shell: interpret an exit code of 77 from scripts as "skipped"

[Thomas Haller <thaller@redhat.com>]

Allow scripts to indicate that a test could not run by exiting 77.

"77" is chosen as exit code from automake's testsuites ([1]). Compare to
git-bisect which chooses 125 to indicate skipped.
