Fix #100: Adjust path to COND_RECONF /var/run symlink may be missing

On systems with the new /run hierarchy the compat symlink from /var/run
may be missing, or not yet be set up by bootmisc.so.  This patch adds a
layer of safety to the condition layer, both set and get cond ops now
perform an adjustmed of the condition path if needed.
