Fix, extend, and clean up command line -t handling. Patch by Andreas
Scherer, modulo some offset shifts probably due to out of order patching:

In its current state of version 0.11.3, debbuild seems to support the
'-t' option with .tar.gz files exclusively. Unzipped .tar files and
bzipped/xzipped .tar files couldn't be properly handled by zcat, nor
could .zip files.

TODO: Try to reduce/merge the three large logic constructs for selecting
"some action" according to the file extension.
