new 'no-dereference' mount option

Browse Source 
Add a new `no-dereference` mount option supported by crun 1.11+ to
re-create/copy a symlink if it's the source of a mount.  By default the
kernel will resolve the symlink on the host and mount the target.
As reported in #20098, there are use cases where the symlink structure
must be preserved by all means.

Fixes: #20098
Fixes: issues.redhat.com/browse/RUN-1935
