[SRU][X][PATCH 1/1] UBUNTU: [Packaging] add support to compile/run selftests

[Kleber Sacilotto de Souza]

BugLink: https://bugs.launchpad.net/bugs/1874286

Add some simple debian/rules targets that will keep a list of the
selftests that Ubuntu cares about, compile and run them. This can be
plugged into our test build infrastructure in order to compile the
testcases before we close and package a release.
