Consider packages with M-A qualifiers for reverse dependencies

Browse Source 
Strip of Multi-Arch qualifiers ":any" and ":native" when building the
dependency fields, as they are not part of the package name.

This will fix cases like

  Package: ipython3
  Depends: python3:any (>= 3)

and include ipython3 in python3's reverse dependencies.

Closes: #794194
