currently FTBFS due to TestTLSConfig

golang-github-prometheus-common package currently FTBFS due to TestTLSConfig

=== RUN TestTLSConfig http_config_test.go:519: Unexpected TLS Config result:

This is reported upstream at https://github.com/prometheus/common/issues/267
This is also already fixed in commit 10e1378a4a94394e5671c529b7d87833c2b70d13

This also appears to be related to go 1.16 - previous versions of go appear to not trigger the issue (or so I infer from the upstream bug report).

Filing the bug largely to track this as a known issue and mark it in the
update-excuses report. Should be resolved when a new version is uploaded, or
the above fix could be cherry-picked if someone is so inclined.

This patch cherry picks a minor upstream change to enable building with golang 1.16.

This bug was fixed in the package golang-github-prometheus-common - 0.15.0-2ubuntu1

---------------
golang-github-prometheus-common (0.15.0-2ubuntu1) impish; urgency=medium

  * Cherry pick code from upstream to fix an issue with RootCA comparison. As
    of go 1.16 these RootCAs will never be equal, so we just compare the
    subjects instead of the entire value. (LP: #1930772)
