software-center mishandles ':any' dependency architecture qualifiers

[Francois Gouget]

Here is how to reproduce this bug:
 * Download http://fgouget.free.fr/bugs/testdep.tar.bz2
   This is a small archive that contains a set of test, empty, Debian
   package files along with their source.
   (run ./build to rebuild them)

 * Install the testdep-allowed_1.0-1_amd64.deb package.

 * Then run: software-center testdep-allowed-any_1.0-1_i386.deb

Software Center will then refuse to install the package with the following error:

    Dependency is not satisfiable: testdep-allowed

Yet testdep-allowed-any has 'testdep-allowed:any' as its sole dependency so the installed amd64 testdep-allowed package should satisfy it. Running dpkg confirms this:

# dpkg -i testdep-allowed-any_1.0-1_i386.deb
Selecting previously unselected package testdep-allowed-any.

That version is no more maintained

Fortunately I can confirm that this bug is no longer present in Ubuntu 15.04's software-center 13.10-0ubuntu6, nor in the 14.04 LTS software-center 13.10-0ubuntu4. So someone must have fixed it somehow.
