file-systems: 'mount-file-system' preserves the right mount flags.

Browse source 
Fixes <https://bugs.gnu.org/47007>.
Reported by Jelle Licht <jlicht@fsfe.org>.

Since commit dcb640f02b, we could end up
applying the wrong mount flags because the (find ...) expression could
pick the "wrong" mount point in the presence of bind mounts.

* gnu/build/file-systems.scm (mount-file-system): Use 'statfs' to
compute FLAGS whe FS is a bind mount.
