inotify: show inotify mask flags in proc fdinfo

mainline inclusion
from mainline-v5.19-rc1
commit a32e697c
category: bugfix
bugzilla: https://gitee.com/openeuler/kernel/issues/I5IHD1
CVE: NA

Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id=a32e697cda27679a0327ae2cafdad8c7170f548f

--------------------------------

The inotify mask flags IN_ONESHOT and IN_EXCL_UNLINK are not "internal
to kernel" and should be exposed in procfs fdinfo so CRIU can restore
them.
