Subject: [PATCH] Documentation/filesystems: sharedsubtree: add section headings

Several of the sections are missing underlines. This makes the
generated contents have missing entries, so add the underlines.

Fixes: 16c01b20ae05 ("doc/filesystems: more mount cleanups")
Fixes: 9cfcceea8f7e ("[PATCH] Complete description of shared subtrees.")
