file-systems: Support the 'remount' mount flag.
This allows remounting file systems which are already mounted by
the initrd with custom mount options (e.g. /proc with hidepid=2).
* gnu/build/file-systems.scm (mount-flags->bit-mask): Map 'remount
to MS_REMOUNT.
* gnu/system/file-systems.scm (invalid-file-system-flags): Add
'remount to the list of KNOWN-FLAGS.
* doc/guix.texi (File Systems): Document it.
Fixes: guix/guix#3849
