ANTLR3: Install into `CMAKE_INSTALL_LIBDIR` (#6912)

On some platforms, autotools installs ANTLR3's libraries into lib but
CMAKE_INSTALL_LIBDIR is set to lib64 (e.g., Fedora 33). This commit
sets --libdir to force autotools to install the library into the
directory specified by CMAKE_INSTALL_LIBDIR.
