app-emulation/protontricks: re-enable tests

Instead of having to jump through hoops to satisfy setuptools-scm,
remove references to that package and seed the version file manually,
using the value of ${PV}. Presto, can use GitHub release archives -
and by extension run tests - again!

+Since version 1.4.1 upstream has used setuptools-scm to determine the
+current version number. Unfortunately the package in question does not
+support GitHub release archives, using GitHub VCS snapshots would require
+retrieving and updating commit hashes corresponding to release tags, and
+PyPI tarballs do not contain tests. setuptools_scm_git_archive does not
+help because it requires extra files to be included in the repository,
+which upstream has not done.
+
+Seeing as we already know the version number, bypass setuptools_scm
+altogether and create the version file ourselves. For obvious reasons the
+latter cannot be done with a patch alone - have to call sed in src_prepare.
