Failed to install on CircleCI

[powerman]

Using current docker image circleci/golang:1 we've this setup:

circleci@34bf5a878789:~$ id
uid=3434(circleci) gid=3434(circleci) groups=3434(circleci)

circleci@34bf5a878789:~$ echo $PATH
/go/bin:/usr/local/go/bin:/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin

Such default $PATH makes it inconvenient to let goreleaser to install to ~/bin, but when I run goreleaser script with -b $(go env GOPATH)/bin option it executes install -d /go/bin, which fails while trying to fchmod it:

circleci@34bf5a878789:~$ install -d /go/bin
install: cannot change permissions of ‘/go/bin’: Operation not permitted

Looks like goreleaser should be fixed to avoid needless install -d in case directory already exists and writable.
