Subject: [PATCH] Add minitest support for file exclude pattern

* Issue https://github.com/renderedtext/test-boosters/pull/72
* Based on rspec support added here https://github.com/renderedtext/test-boosters/pull/72
* Adds support for minitest include and exclude patterns based on
  `TEST_BOOSTERS_MINITEST_TEST_FILE_PATTERN` and
  `TEST_BOOSTERS_MINITEST_TEST_EXCLUDE_PATTERN` env vars.
