Benjamin Coddington a002ad8a9b NFSD/export: Add sign_fh export option ...

In order to signal that filehandles on this export should be signed, add a
"sign_fh" export option.  Filehandle signing can help the server defend
against certain filehandle guessing attacks.

Setting the "sign_fh" export option sets NFSEXP_SIGN_FH.  In a future patch
NFSD uses this signal to append a MAC onto filehandles for that export.

While we're in here, tidy a few stray expflags to more closely align to the
export flag order.
