[fprintd/f14/master] Don't every allow pam module to get unloaded

[Ray Strode]

commit 137088124a18ba781e11541ed6ab7033ab92b4b3
Author: Ray Strode <rstrode at redhat.com>

    Don't every allow pam module to get unloaded
    
    The PAM module uses dbus-glib, static gobject types, etc,
    so it really can't get unloaded.
    
    This commit adds some linker-fu to keep it resident even
    after the pam module closes.
