file-systems: Always write the options field in /etc/mtab.

Browse source 
* gnu/build/file-systems.scm (mount-file-system): When OPTIONS is false,
  write "rw" to /etc/mtab.  This fixes a bug whereby 'remove-from-mtab'
  in (guix syscalls) would otherwise raise a 'match-error' because of
  the missing field.  This affected file systems mounted from the
  initrd, such as devtmpfs, which has options == #f.
