Add more sanity tests for grep, egrep, and fgrep

Browse Source 
The test suite currently lacks basic sanity checks to ensure that egrep,
fgrep, and grep are actually matching the right expression types, i.e. passing
the right flags to regcomp(3). Amend the test suite to make sure that not only
are the individual versions doing the right thing, but also that we don't have some
kind of frankenregex situation happening where egrep is accepting a BRE or
grep an ERE.

I've chosen to not expand the 'basic' test but to add the 'grep_sanity' checks
to their own test case since this is testing for more than just 'grep matches things',
but actual expression types.
