Djalal Harouni bc452b4b65 proc: do not allow negative offsets on /proc/<pid>/environ ... __mem_open() which is called by both /proc/<pid>/environ and /proc/<pid>/mem ->open() handlers will allow the use of negative offsets. /proc/<pid>/mem has negative offsets but not /proc/<pid>/environ. Clean this by moving the 'force FMODE_UNSIGNED_OFFSET flag' to mem_open() to allow negative offsets only on /proc/<pid>/mem.
