Bug#869511: linux: binNMU-unsafe dependency on linux-headers-*-common

["Aaron M. Ucko" <ucko@debian.org>]

Source: linux
Version: 4.11.11-1
Severity: grave
Justification: renders package unusable (uninstallable)

The recent binNMU of linux for Perl 5.26 broke the build-specific
headers packages, which are architecture-dependent but depend on an
identical *binary* version of the architecture-independent
linux-headers-*-common package.  Specifically, I observe that
linux-headers-4.11.0-2-amd64 4.11.11-1+b1 depends on
linux-headers-4.11.0-2-common (= 4.11.11-1+b1), which does not exist.

Could you please fix these relationships to use ${source:Version}?
(As you may recall, the legacy ${Source-Version} variable is an alias
for *${binary:Version}*.)

Thanks!
