match: use match.prefix() in subdirmatcher
It seems like the subdirmatcher should be checking if the matcher it's
based on is matching prefixes. It was effectively doing that already
because "prefix() == not always() and not anypats() and not
isexact()", subdirmatcher was checking the first two parts of that
condition and I don't think it will ever be given an "exact" matcher
with it's directory name (because exact matchers are for matching
files, not directories). Still, let's switch to using prefix() for
clarity (and because I'm trying to remove code that reaches for
matchers internals).
