filter out ":amd64" string when comparing new installed packages name…

[alex-tu-cc]

… (#47)

because of some installed package have postfix ":amd64", it will
confuse the logic of commit "f352bd" for #28 and treat it as a failure.

Thanks for finding this. I think it would be be better to be architecture independent if possible (same problem could technically happen for i386 or any other architecture). Perhaps can you query the following to build the list?

# dpkg --print-architecture
# dpkg --print-foreign-architectures

I think that would be more future proof. Otherwise this looks good to me.

Thanks for superm1's suggestion, and uploaded a new commit 8764f,
so now it could be used on each architecture.

I have verified these commits but they didn't really fix the issue.

Looks good, but if it doesn't fix the issue, what else is needed? I guess i'll hold off to merge until you guys say it's good.

the issue was happen to 2nd commit for supporting other architecture than amd64, it caused by single quote which will treat $(dpkg --print-architecture) as string.

I force pushed the modification to 193972905e1e6f7d74778fd47a6e4b27f6483d16 to use double quote instead. It works fine on my machine now :)
