[PATCH] dir: use fspathncmp() in pl_hashmap_cmp()

[René Scharfe]

From: Jeff King <peff@peff.net>

Call fspathncmp() instead of open-coding it.  This shortens the code and
makes it less repetitive.

That's an old one. :) Thanks for hanging on to it.

Unlike the other one discussed in that thread, where there is a shadow
ignore_case, we decided that this one is a true simplification.
