go: security bump to version 1.10.2

This bump contains many bug fixes, as well as the following security
issue, patched in Go 1.10.1:

CVE-2018-7187: The "go get" implementation in Go 1.9.4, when the
-insecure command-line option is used, does not validate the import path
(get/vcs.go only checks for "://" anywhere in the string), which allows
remote attackers to execute arbitrary OS commands via a crafted web
site.
