tests: optionally skip bin-wrappers/

This speeds up the tests by a bit on Windows, where running Unix shell
scripts (and spawning processes) is not exactly a cheap operation.

+--no-bin-wrappers::
+       By default, the test suite uses the wrappers in
+       `../bin-wrappers/` to execute `git` and friends. With this option,
+       `../git` and friends are run directly. This is not recommended
+       in general, as the wrappers contain safeguards to ensure that no
+       files from an installed Git are used, but can speed up test runs
+       especially on platforms where running shell scripts is expensive
+       (most notably, Windows).

        Create "trash" directories used to store all temporary data during
        testing under <directory>, instead of the t/ directory.
