Subject: [PATCH] Add RemoveIPC=no to login config

The default setting of RemoveIPC=yes for systemd-logind creates problems
when non-system users (UID>1000) start daemons, which use System V
semaphores and which should keep running when they log out their
session. This is the case for postgreSQL.

Install systemd-loging drop-in configuration file which sets
`RemoveIPC=no`.
