Make SSLConfigManager notify clients if the SHA-1 policy changes

An oversight in the comparator for the SSLConfigManager that handles
the logic for determining when an SSLConfig is "new" (and thus
should invalidate all existing SSLConfigs) meant that changes to the
SHA-1 policy for local anchors wouldn't be immediately propagated.
