osd: change lvm bindmount

This commit makes the bindmount a bit more generic, otherwise it
currently makes the OSDs failing to start in an OSP FFU upgrade
(with RHEL7 > RHEL8 OS upgrade).
docker2podman playbook is run from ceph-ansible stable-3.2 branch
against RHEL7 nodes where `/var/run/lvmetad.socket` exists but once the
system is upgraded to RHEL8, this socket doesn't exist anymore and
prevent OSDs from starting after the reboot.

As a workaround we can make this bindmount a bit more generic like what
is done in `stable-4.0` branch by mounting `/run/lvm` instead.
