channels: Call 'build-self.scm' procedure with a trivial build handler.
Previously, "TESTS=installed-os guix build -m etc/system-tests.scm"
would repeat the "Computing Guix derivation" phase ~5 times due to the
fact that there were several call paths, within a build-accumulator,
leading to (package-derivation store guix).
* guix/channels.scm (with-trivial-build-handler): New procedure.
(build-from-source): Wrap 'build' call in 'with-trivial-build-handler'.
