Add ability to filter out results of https://docs.python.org/3/library/shutil.html#shutil.which by https://docs.python.org/3/library/os.html#os.stat_result.st_flags

Pitch

• https://en.wikipedia.org/wiki/System_Integrity_Protection
• Impossible to passthru / set DYLD_LIBRARY_PATH on macOS pypa/hatch#701 (comment)

Basically, it is desirable to call/use a version of an installed executable that is not restricted by macOS SIP such as when modifying linker environment variables.
