import: dpkg-source emits a fatal error with bad control files

[Nish Aravamudan]

Rather than printing the source which it can still determine. I think this is an ordering issue in dpkg's source, which we might want to work around.

  dpkg-source: error: binary package stanza libc-bin is using an obsolete Build-Profiles field syntax

Because the profile is not enclosed in <>.

We could either patch dpkg in the snap (in which case I think we should file a bug upstream); or we could patch the source before import (but this could happen with a lot of old packages).

a patch like
              http://paste.ubuntu.com/25676319/ which results in (IMO) improved
              behavior as: http://paste.ubuntu.com/25676320/

Note that after reading the code, we fallback to manual reading of the d/s/format file if it exists, so it's not terrible. But we should make this less noisy.
