Subject: [PATCH] depends: Fix build with `MULTIPROCESS=1` in Guix environment

In the Guix environment, `${BASEPREFIX}/${HOST}/native/bin` is added to
the `PATH` environment variable, causing CMake to search for package
configurations in the `native` subdirectory first.

Explicitly specifying the top-priority search prefixes for the
`Libmultiprocess` and `LibmultiprocessNative` packages resolves the
issue.
