Subject: fix rpath string memory leak on failed dlopen
X-Git-Tag: v1.1.9~90

fix rpath string memory leak on failed dlopen

when dlopen fails, all partially-loaded libraries need to be unmapped
and freed. any of these libraries using an rpath with $ORIGIN
expansion may have an allocated string for the expanded rpath;
previously, this string was not freed when freeing the library data
structures.
