Go master contains the commit hash that it was built at (or some similar
token). Unfortunately our regexp that we were checking against had an
escaping error.
grep -q 1.9
instead ofgrep -q 1\.9
which meant itwas matching 1[any character]2. The current golang master commit is
"go version devel +15bc0a129a Wed Jan 3 04:34:11 2018 +0000 linux/amd64"
Fixes by making the string A LOT more specific and escaping.
