[patch] fall back to using MAP_PRIVATE with mmap() in fbcon driver

SDL Development
1

trying to use MAP_SHARED with mmap() on uClinux (aka non-mmu) hosts nowadays
will simply fail since the kernel disallows it … falling back to using
MAP_PRIVATE on these hosts is acceptable … as such, ive attached a patch
for the fbcon driver that will fall back to using MAP_PRIVATE if mmap() with
MAP_SHARED failed

going by a grep of MAP_SHARED, the only other drivers that utilize this flag
are video/wscons, video/ps2gs, and sound/dmaaudio … i dont think these
would appear on a non-mmu host so the patch i wrote is restricted to just
SDL_fbvideo.c …
