build-system/go: Initialize build cache from input packages.
* guix/build/go-build-system.com (setup-go-environment): Set GOCACHE to
a location within the build directory. Union "/var/cache/go/build"
input directories to initialize the cache. Generate "trim.txt" within
the cache, with the current time.
