Build: lrmd doesn't need to be linked against liblrmd

...which is sort of a paradox, but the truth is that pacemaker_remoted
(slightly different and extended build of lrmd) requires that linkage.

Discovered by looking at how the linkage looks like after introduction
of "ld --as-needed" (consider only libraries actually satisfying symbol
resolution, commit 5ec2711) for daemons + libraries.
