perf tools: fix off-by-one error in maps
This patch fixes off-by-one errors in the management of maps.
A map is defined by start address and length as implemented by
map__new():
map__init(map, type, start, start + len, pgoff, dso);
map->start = addr;
map->end = end;
Consequently, the actual address range is [start; end[ map->end is the
first byte outside the range.
This patch fixes two bugs where upper bound checking was off-by-one.
In V2, we fix map_groups__fixup_overlappings() some more where
map->start was off-by-one as reported by Jiri.
