pkg/44713, brokennes of GNU patch

[Aleksey Cheusov <cheusov%tut.by@localhost>]

Hello. GNU patch fails to apply pkgsrc patches correctly (see
http://gnats.netbsd.org/44713).  Another problem is that latest versions
of GNU patch exit with error if files to be modified are read-only. This
happens very often with pkgsrc distfiles.

In order to solve this problem I'd like to enable devel/nbpatch
unconditionally during bootstrap on Linux and Solaris.
Then close pkg/44713.

Objections? The patch is in attachment.
