src: reduce duplication in RegisterHandleCleanups

This commit suggest using a lambda for the RegisterHandlerCleanup calls
in RegisterHandleCleanups.

The motivation is to reduce some duplication and to make it a little
easier to read as all of the calls pass in the same arguments, apart
from casting the uv handle.
