In Gentoo, the openrc init framework creates the /dev/shm location (within
devtmpfs) using a "mkdir -m 1777 /dev/shm" command. This results in initrc_t
wanting to set the attributes of the /dev/shm directory (at that point still
labeled device_t as tmpfs isn't mounted on it yet).

This interface will be used by domains that need to manage the various pidfile
content (*_var_run_t).

Gentoo's OpenRC init framework handles the migration of data from /var/run to
/run, and /var/lock to /run/lock. To deal with this, openrc uses "cp -a -r
/var/run /run" and "cp -a -r /var/lock/* /run/lock".
When done, it will create symlinks in /var towards the new locations.
As a result, initrc_t needs to be able to manage symlinks in /var, as well as
manage all pidfile content (needed for the migration of /var/run/* towards
/run).

Currently, the files_manage_generic_locks only handles the lock files. If a
domain needs to manage both lock files and the lock directories (like specific
subdirectories in /var/lock that are not owned by a single other domain, such as
Gentoo's /var/lock/subsys location) it also needs the manage permissions on the
directory.
This is to support OpenRC's migration of /var/lock to /run/lock which otherwise
fails:
* Migrating /var/lock to /run/lock
cp: cannot create directory '/run/lock/subsys': Permission denied
rm: cannot remove '/var/lock/subsys': Permission denied
