debian: Make all binary packages depend on ${misc:Depends}.
According to lintian:
> The source package uses debhelper but it does not use ${misc:Depends} in
> the given binary package's debian/control entry. This is required so the
> dependencies are set correctly in case the result of a call to any of
> the dh_ commands cause the package to depend on another package.
Fixed by adding ${misc:Depends} as a dependency to all binary packages that
didn't already have it.
