exportfs: reallow building as a module
exportfs: reallow building as a module

Commit 990d6c2d7aee921e3bce22b2d6a750fd552262be ("vfs: Add name to file
handle conversion support") changed EXPORTFS to be a bool.
This was needed for earlier revisions of the original patch, but the actual
commit put the code needing it into its own file that only gets compiled
when FHANDLE is selected which in turn selects EXPORTFS.
So EXPORTFS can be safely compiled as a module when not selecting FHANDLE.
