docs: fs: convert docs without extension to ReST
There are 3 remaining files without an extension inside the fs docs
dir.
Manually convert them to ReST.
In the case of the nfs/exporting.rst file, as the nfs docs
aren't ported yet, I opted to convert and add a :orphan: there,
with should be removed when it gets added into a nfs-specific
part of the fs documentation.
