Fix build-cli-bin to use generated templates (linkerd#2341)

The `bin/build-cli-bin` script, intended to build a local `linkerd` cli
binary, was compiling the binary configured to read template files out
of the local machine's GOPATH.

This change modifies `build-cli-bin` to build a `linkerd` binary the
same way `docker-build-cli-bin` does. Specifically, by generating static
template files for inclusion in the build, and adding the `-tags prod`
flag to ensure those files are compiled in.
