[PATCH] Makefile: promote wildmatch to be the default fnmatch implementation

["Nguyễn Thái Ngọc Duy" <pclouds@gmail.com>]

This makes git use wildmatch by default for all fnmatch() calls. Users
who want to use system fnmatch (or compat fnmatch) need to set
NO_WILDMATCH flag.

wildmatch is a drop-in fnmatch replacement with more features. Using
wildmatch gives us a consistent behavior across platforms. The
tentative plan is make it default with an opt-out for about 2 cycles,
then remove NO_WILDMATCH and compat/fnmatch.
