meson: Update lua wrap to 5.4.6-4
This version of the lua wrap fixes installation of the library which was previously causing liblua SOs to be missing when Mesa was installed using meson install, ninja install, etc. These dynamic linker would attempt to find these at runtime and fail to find them unless it could grab them from an external package. With this change, three SOs for liblua are copied to the library install directory:
liblua.soliblua.so.5.4liblua.so.5.4.6
