devel/smokegen: Rework RPATH fix

Although my fix was clever, it was unnecessary.  As soon as cmake was
instructioned to insert RPATH again, the embedded gcc rpath came back
so /usr/lib/gccXX was duplicated.  Just remove it, and let /usr/local/lib
get picked up with ldconfig so no substitution is needed anymore.
