integration_test.go: move Go cache

Browse Source 
Move the Go cache from .cache/gocache to .gocache.
This moves it out of the .cache directory so that Travis-CI will
not cache the Go cache.

Unfortunately, the Go toolchain's caching algorithm is not
aggressive enough in evicting old entries, causing Travis-CI
to keep caching an ever growing Go cache.
We're at the point where network IO moving a massive Go cache
is more costly than not having it at all.
