motion: update to 4.3.1

Remove upstreamed patch.

Added patch to remove man and po stuff to fix compilation and speed up
the build.

Added PKG_BUILD_PARALLEL for faster builds.

Added PKG_INSTALL for consistency between packages. Used those install
paths as well to make it easier.

Other small cleanups for consistency between packages.
