[PATCH nft 1/1] tests/shell: accept name of dump files in place of test names

[Thomas Haller <thaller@redhat.com>]

Imagine you have the filename of a dump file at hand. For example, because
it shows up in `git status` and you can copy it from the terminal.

If you want to run the corresponding test, that was cumbersome. It
involved editing the command line (removing the /dumps/ directory and
the file suffix).

Instead, let "run-tests.sh" do that automatically. There is little value
in bothering the user with a failure:

Before:

  $ ./tests/shell/run-tests.sh tests/shell/testcases/optionals/dumps/comments_table_0.json-nft -L
  E: Unknown test "tests/shell/testcases/optionals/dumps/comments_table_0.json-nft"

After:
  $ ./tests/shell/run-tests.sh tests/shell/testcases/optionals/dumps/comments_table_0.json-nft -L
  tests/shell/testcases/optionals/comments_table_0
