95cd815c36 swscale: try to use mmap only if available 
Some systems, e.g. Minix, have sys/mman.h defining MAP_ANONYMOUS without
providing (working) mmap and friends.  The mmx filter generation code
checks only for MAP_ANONYMOUS, not for availability of mmap itself which
leads to build errors on aforementioned systems.

This changes the conditional compilation to use mmap only if all the
required functions are available.
