tree-wide: no need to pass excess flags to open()/openat() if O_PATH is passed
As described in the documentation: When O_PATH is specified in flags, flag bits other than O_CLOEXEC, O_DIRECTORY, and O_NOFOLLOW are ignored. So, we can remove unnecessary flags in a case when O_PATH is passed to the open() or openat().
