Modified Files:
	rclone/Makefile

Log Message:
rclone: Use lang/go/go-package.mk and `do-install'

For Go packages that just install a binary we can just use
lang/go/go-package.mk, set GO_DIST_BASE and GO_SRCPATH and then define a
`do-install' target to just install the binary.

Thanks again to <bsiegert> for the suggestions!
