Get error from dln_open when USE_SHARED_GC

Browse source 
Before, if dln_open failed to open RUBY_GC_LIBRARY_PATH, it would segfault
because it would try to raise an error, which cannot happen because the
GC has not been initialized yet.

This commit changes dln_open to return the error that occurred so the
caller can handle the error.
