package/cmake: propagate libuv dependencies

In c2c06a6de02,  cmake version was bumped and a new dependency on libuv
was added, but it did not propagate all the dependencies of libuv,
missing sync_4 (probably because sync_4 was added after the patch was
sent on the list, but before it was applied to the tree).

Fix that, which fixes unmet dependencies.
