ci: fix broken build

The master build is currently failing because of golang.org/issue/44106.
The part of CI that is failing is a sanity check that that ensures we
can pull cuelang.org/go through proxy.golang.org. This network-dependent
test only needs to run on master commits (indeed it doesn't make sense
for CLs).

Work around that by doing a go get -d on cuelang.org/go/cmd/cue.
