Only attempt to open files having the proper prefix. For example, slurmd
should never even try to dlopen a plugin with a prefix of "jobcomp" as
doing so both wastes time and generates undefined external errors (the
jobcomp plugin is written for the slurmctld daemon and only it has the
proper external function to dlopen that plugin).
