[PATCH nft 3/3] tests/shell: colorize NFT_TEST_HAS_SOCKET_LIMITS

[Thomas Haller <thaller@redhat.com>]

NFT_TEST_HAS_SOCKET_LIMITS= is similar to NFT_TEST_HAVE_* variables and
indicates a feature (or lack thereof), except that it's inverted.  Maybe
this should be consolidated, however, NFT_TEST_HAS_SOCKET_LIMITS= is
detected in the root namespace, unlike the shell scripts from features.
So it's unclear how to consolidate them best.

Anyway. Still highlight a lack of the capability, as it can cause tests
to be skipped and we should see that easily.
