Support: arch spec constraint

[eldesh]

I added architecture restrictions syntax like below:

# Cargo.toml
..
depends: foo [!i386], bar [amd64], buzz [armhf]
..

For this file, if you build a package like cargo deb --target=arm-unknown-linux-gnueabihf, resulting .deb contains only foo and buzz like:

Depends: foo, buzz

Specification strings (e.g. [i386]) and dependencies not match to the build target (i.e. arm) are eliminated from cargo-deb.

Thanks. That's a nice feature.

Since you're using regex, maybe extract the arch using regex instead of chopping the string "manually" afterwards?

Thank you for your feedback. I have fixed manual chopping to use regex capture.
