Linux: Prefer own symbols in libnode.so
Linux: Prefer own symbols in libnode.so

Fix crash in CentOS 7.6 when requiring crypto. The system has a
libcrypt which conflicts with the symbols in libnode. It was
calling OBJ_NAME_add in libcrypt and crash there. The system libcrypt
is needed by libcups, on which NW depends.

Fix #6928
