Merge branch 'jm/t0213-skip-emulated-ancestry-tests'

The 'TRACE2_ANCESTRY' prerequisite in the 't0213' test script has been
refined to avoid failures under user-mode emulation by verifying that
the ancestry collector reports the expected process names rather than
the emulator binary name.

  t0213: skip ancestry tests under user-mode emulation
