Subject: [PATCH] verify-no-vendor-cycles: set up Go environment

This script relies on Go but doesn't set up the private Go environment
(which ensures that the go command meets k/k's requirements). This
fixes that.

As a drive-by improvement, drop two unnecessary backslashes from
regexes (before / which doesn't need to be escaped).
