[PATCH v8 16/16] fix: support build of packages with epoch version

[Uladzimir Bely <ubely@ilbers.de>]

From: Felix Moessbauer <felix.moessbauer@siemens.com>

This patch reworks the logic how the DSC file for building
with sbuild is located.
By that, we do not rely on implementation details of dpkg-source
regarding the name of the generated .dsc file.
Instead, we remove all <package>*.dsc files in advance, let dpkg-source
generate the file and use a find to locate the generated one.

By that, package versions with epochs (e.g. "1:1.0.0") are
supported.
