This reverts commit 6355e75610.
The previously mentioned commit inadvertently broke a lot of SELinux related
functionality for both unprivileged users and systemd instances running as
MANAGER_USER. In particular, setting the correct SELinux context after a User=
directive is used would fail to work since we attempt to set the security
context after changing UID. Additionally, it causes activated socket units to
be mislabeled for systemd --user processes since setsockcreatecon() would never
be called.
Reverting this fixes the issues with labeling outlined above, and reinstates
SELinux access checks on unprivileged user services.
