Ticket 48849 - Systemd introduced incompatible changes that breaks ds build

Bug Description:  In rawhide systemd removed a number of libraries in favour
of a monolithic version. This breaks our build that expected systemd modules.

Fix Description:  Change our systemd.m4 to use the monolithic library
