[pkg-gnupg-maint] Bug#834602: dirmngr/gnupg: dependencies not strict enough

[Ansgar Burchardt]

Package: dirmngr
Version: 2.1.14-5
Severity: normal

The dependencies between dirmngr and gnupg2 are not strict enough and
allow installing non-working combinations, such as dirmngr=2.1.11-7
(from testing) and gnupg=2.1.14-5 (from unstable):
