Applied perl FKO module libfko path patch from Franck Joncourt

Applied patch from Franck Joncourt to have the perl FKO module link
against libfko in the local directory (if it exists) so that it doesn't
have to have libfko completely installed in /usr/lib/.  This allows the
test suite to run FKO tests without installing libfko.

Added the ability to the test suite to compile, install, and run some
basic tests against the perl FKO module.
