[PATCH 2/9] man/man2/statmount.2: Document STATMOUNT_MNT_OPTS

Document STATMOUNT_MNT_OPTS flag and the corresponding field introduced
by it.

STATMOUNT_MNT_OPTS is used to get all mount options on the mount
separated by commas. Similiar to how they are displayed in
/proc/[pid]/mountinfo.

This text is based on this commit [1].
