[OE-core] clutter: clutter_git is really clutter-1.8_git, rename

[Richard Purdie]

Both these clutter recipes provide 1.8. With different PN namespace, a world
build cna build both causing the clutter libraries to "disappear" at certain
points of the build. In particular, this causes issues for mx.

This patch puts then into the same PN namespace so only one can be built.
