selects tests based on pattern of TESTS environment variable.

2022-01-14  Mohammad-Reza Nabipoor  <mnabipoor@gnu.org>

        * testsuite/lib/poke.exp (tests_pattern): New variable.
        (tests_pattern_pk): Likewise.
        * testsuite/poke.cmd/cmd.exp: Use `tests_pattern`.
        * testsuite/poke.map/map.exp: Likewise.
        * testsuite/poke.pickles/pickles.exp: Likewise.
        * testsuite/poke.pkl/pkl.exp: Likewise.
        * testsuite/poke.pktest/pktest.exp: Likewise.
        * testsuite/poke.std/std.exp: Likewise.
        * testsuite/poke.time/time.exp: Likewise.
