[pkg-go] Bug#911912: golang-github-gin-gonic-gin FTBFS: missing Build-Depends: tzdata

[Helmut Grohne]

Source: golang-github-gin-gonic-gin
Version: 1.3.0+dfsg1-2
Severity: serious
Tags: ftbfs patch

golang-github-gin-gonic-gin fails to build from source when tzdata is
not present in the chroot. While our autobuilders do install it (due to
debootstrap installing Priority: required), it is neither essential nor
build-essential. If it goes missing, tests fail:

Please add "tzdata <!nocheck>" to Build-Depends.
