[PATCH nft 4/6] tests/shell: special handle base path starting with "./"

[Thomas Haller <thaller@redhat.com>]

When we auto detect the tests with `tests/shell/run-tests.sh -L`, then
commonly the NFT_TEST_BASEDIR starts with a redundant "./". That's a bit
ugly.

Instead, special handle that case and remove the prefix. The effect is
that `tests/shell/run-tests.sh -L` shows

  tests/shell/testcases/bitwise/0040mark_binop_0

instead of

  ./tests/shell/testcases/bitwise/0040mark_binop_0
