perf symbols: Make sym->end be the first address after the symbol range
To follow vm_area_struct->vm_end convention. By adhering to the convention that ->end is the first address outside the symbol's range we can do things like: sym->end = start + len; len = sym->end - sym->start; This is also now the convention used for struct map->end, fixing some off-by-one bugs.
