[pkg-gnupg-maint] Bug#845565: reducing severity of #845565

[Daniel Kahn Gillmor]

Control: severity 845565 normal

Please avoid severity inflation!  "grave" means "makes the package in
question unusable by most or all users", and i don't believe that is the
case.  Most users can use pinentry successfully, we're just establishing
the specific use cases where y'all are seeing failures (ssh'ing into
machines which have concurrent graphical sessions is not a common
pattern afaict).

Regards,
