[PATCH] tests: grep portability fixes

We try to avoid using the "-q" or "-e" options, as they are
largely useless, as explained in aadbe44f.

There is one exception for "-e" here, which is in t7701 used
to produce an "or" of patterns. This can be rewritten as an
egrep pattern.

This patch also removes use of "grep -F" in favor of the
more widely available "fgrep".

Other than that, this looks good after a quick scan.

Doesn't output need to be redirected when you drop '-q'?

In standard mode, the test output is directed to /dev/null anyway, and in
verbose mode the extra output doesn't hurt at all, and is usually useful
because you know that a pattern matched.

Thanks Mike and Johannes. The dropping of "-e" and "-q" we had done
before, but this was our first use of egrep and fgrep. From my
(admittedly limited) knowledge, I think they are fine, but it is nice to
have some confirmation.

Exactly. This is the more of the same as aadbe44f (grep portability fix:
don't use "e" or "-q") but I was too lazy to rewrite the justification
completely (but I did reference it).
