Fix 'mprotect remapping failed' abort on NetBSD with PaX enabled
(a cherry-pick of commit 1b28cc4b from 'release-7_4')

Issue #255 (bdwgc).

Without this patch, GC_remap() works on NetBSD which has the PaX feature
only if PaX MPROTECT is off (sysctl -w security.pax.mprotect.enabled=0).

* os_dep.c [USE_MUNMAP && !MSWIN32 && !MSWINCE && NETBSD] (GC_remap):
Call mmap() instead of mprotect().
