Update container Mounted() and Mountpoint() functions

Addresses a regression in `podman mount` due to our mount changes
to allow concurrency by letting c/storage handle mounting and
unmounting.

Combine Mounted() and Mountpoint() into one function and query
c/storage directly to ensure we get accurate information.
