With commit 42c0e5bb05 ("test: Find leftovers after clean/mrproper")
we assume that we are performing out of tree builds. test_clean and
test_mrproper fail if the assumption isn't met.
However there are valid scenarios where tests run with in source builds
(i.e., test.py --build-dir=.).
Automatically skip cleanup tests in such scenarios to prevent false
positives.

Docs describe 'make clean' to delete most generated files, 'make
mrproper' to delete current configuration and all generated files. This
test tries to assert it.
Idea is to search remaining files by patterns in copies of the initial
out-of-source build, which has two advantages:
- looking in an out-of-source build dir allows to tell generated source
code from committed source code
- copying is fast (compared to rebuilding each time) which allows to do
a "world clean"
