minikube: switch to build from source & fix on Darwin

Linux behavior should be largely unchanged but we now build minikube
ourselves. Unfortunately localkube is still tricky to build so I pull in
a binary version from upstream.

# Normally, minikube bundles localkube in its own binary via go-bindata. Unfortunately, it needs to make that localkube
# a static linux binary, and our Linux nixpkgs go compiler doesn't seem to work when asking for a cgo binary that's static
# (presumably because we don't have some static system libraries it wants), and cross-compiling cgo on Darwin is a nightmare.
#
# Note that minikube can download (and cache) versions of localkube it needs on demand. Unfortunately, minikube's knowledge
# of where it can download versions of localkube seems to rely on a json file that doesn't get updated as often as we'd like,
# so for example it doesn't know about v1.5.3 even though there's a perfectly good version of localkube hosted there. So
# instead, we download localkube ourselves and shove it into the minikube binary. The versions URL that minikube uses is
# currently https://storage.googleapis.com/minikube/k8s_releases.json. Note that we can't use 1.5.3 with minikube 0.17.1
# expects to be able to pass it a command-line argument that it doesn't understand. v1.5.4 and higher should be fine. There
# doesn't seem to ae any official release of localkube for 1.5.4 yet so I'm temporarily grabbing a version built from the
# minikube CI server.
