Subject: [PATCH] tests.auto-patchelf-structured-log: init

This adds a test for the --structured-log feature of auto-patchelf.

When auto-patchelf'ing ToneLib-Jam and only making freetype available,
we expect:

 - one "SetInterpreter" line
 - 3 "Dependency" lines (of which one found)
 - one SetRpath line (containing freetype)
