grep: add tests for grep pattern types being passed to submodules 

Add testing for grep pattern types being correctly passed to
submodules. The pattern "(.|.)[\d]" matches differently under
fixed (not at all), and then matches different lines under
basic/extended & perl regular expressions, so this change asserts that
the pattern type is passed along correctly.
