Mount the base directly on /sysroot in all UC modes, while for hybrid
we mount /run/mnt/data instead of the /run/mnt/sysroot symlink that
was pointing to the former. With this change we do not need to have
the /run/mnt/base mount anymore.

Opening as draft as we will need canonical/core-initrd#265 landed first. As a side note, we should discuss how to handle this initramfs/snap-bootstrap interlocks in an easier way.

Not really, as the new mount unit has an After=snap-initramfs-mounts.service dependency
