Rename localtime.c.patched to localtime.patched.c to keep the correct
language suffix.
Create localtime.patched.c in the build dir rather than in the source
dir. Decouple the build rule for creating localtime.patched.c from
the rule to build localtime.o, so we don't have to rebuild the patched
source file all the time.

That also requires a small tweak to localtime.c.patch, otherwise
GCC complains about the position of the 'trydefrules' label.
Also, simplify includes.

Add tz_posixrules.h with data generated from most recent Cygwin tzdata
package. Establish localtime.cc as primarily a wrapper around a patched
copy of localtime.c. See README for more information.
