systemd: introduce an interface for services using PrivateDevices=yes
...
When a service is configured with PrivateDevices=yes, its /dev directory
has label tmpfs_t. This requires allowing more accesses in order for the
service to use /dev.
This is related to https://github.com/SELinuxProject/refpolicy/pull/61

This patch adds an interface to manage systemd_passwd_var_run_t symlinks that

It has a number of changes needed by systemd_logind_t to set permissions for

It has some more permissions that systemd_machined_t needs, I don't think it's
everything that systemd_machined_t needs but it's a start.
It has some changes for udev_t for systemd-udevd.
