Bug#911580: [britney2] missing trigger with breaks relationship

[Gianfranco Costamagna <locutusofborg@debian.org>]

Package: release.debian.org
User: release.debian.org@packages.debian.org
Usertags: britney
Severity: normal

As said, britney fails to add the appropriate trigger for virtualbox
when a major release is out, and for this reason the ext-pack fails to
install reliably on ci.d.o without additional manual triggers.

"virtualbox (>= 5.2.20-dfsg-0~) | virtualbox-5.2,  virtualbox (<< 5.2.20-dfsg-z) | virtualbox-5.2"

should be a valid relationship.

thanks for having a look,

Gianfranco
