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