Package: python-apt
Version: 0.9.3.6
Severity: normal

Dear Maintainer,

python-apt fails to find installed packages of different architecture
when reading metadata from a deb file. For example, I've installed
libopenjpeg5:i386 on an amd64 system:


```
$ apt-cache policy libopenjpeg5:i386
libopenjpeg5:i386:
  Installed: 1.5.2-2
  Candidate: 1.5.2-2
  Version table:
 *** 1.5.2-2 0
        500 http://ftp.cn.debian.org/debian/ unstable/main i386 Packages
        100 /var/lib/dpkg/status

limbo@Skypiea in ~/.vim/bundle/YouCompleteMe [master]
$ apt-cache policy libopenjpeg5
libopenjpeg5:
  Installed: (none)
  Candidate: 1.5.2-2
  Version table:
     1.5.2-2 0
        500 http://ftp.cn.debian.org/debian/ unstable/main amd64 Packages
```

But when I use python-apt to read the deb file, it reports that this
package is NOT installed on my system:

```python
from apt.debfile import DebPackage
pkg = DebPackage('/var/cache/apt/archives/libopenjpeg5_1.5.2-2_i386.deb')
print pkg.compare_to_version_in_cache() == DebPackage.VERSION_SAME # => False
print pkg.compare_to_version_in_cache() == DebPackage.VERSION_NONE # => True
```

I think the problem resides in function `compare_to_version_in_cache()`
in `debfile.py`, which does not check package names appended with
architecture name suffix.
