services: base: Honor file-system-create-mount-point? at all times.
Fixes <https://issues.guix.gnu.org/40158>.

* gnu/services/base.scm (file-system-shepherd-service): Update doc.  Return a
shepherd service for the mount point when either MOUNT? or CREATE? is true.
[start]: Only mount when MOUNT? is true.
(file-system-shepherd-services): Also consider file systems with
create-mount-point? set to #t.
