Respect the original layout of the atf-{c,c++} tests.

Put test programs for internal modules into a 'detail' subdirectory of the
libatf-c and libatf-c++ test directories, just as the upstream distribution
does. This is necessary because the tests assume such layout to find the
process_helper program, and currently fail because of this divergence.
