tools/testing/selftests/vm/map_fixed_noreplace.c: add test for MAP_FIXED_NOREPLACE
Add a test for MAP_FIXED_NOREPLACE, based on some code originally by Jann
Horn. This would have caught the overlap bug reported by Daniel Micay.
I originally suggested to Michal that we create MAP_FIXED_NOREPLACE, but
instead of writing a selftest I spent my time bike-shedding whether it
should be called MAP_FIXED_SAFE/NOCLOBBER/WEAK/NEW .. mea culpa.
