Ævar Arnfjörð Bjarmason 45d1f37ccc grep: drop support for \0 in --fixed-strings <pattern> ...

Change "-f <file>" to not support patterns with a NUL-byte in them
under --fixed-strings. We'll now only support these under
"--perl-regexp" with PCRE v2.

A previous change to grep's documentation changed the description of
"-f <file>" to be vague enough as to not promise that this would work.
By dropping support for this we make it a whole lot easier to move
away from the kwset backend, which we'll do in a subsequent change.
