This update for systemd contains the following fixes:

- testsuite: move a misplaced %endif

- Do not remove existing configuration files in /etc. If these files were
  modified on the systemd, that may cause unwanted side effects (bsc#1226415).

- Import upstream commit (merge of v254.13)
  Use the pty slave fd opened from the namespace when transient service is running in a container.
  This revert the backport of the broken commit until a fix is released in the v254-stable tree.

- Import upstream commit (merge of v254.11)
