jsoncpp: fix run-ptest with busybox sed

run-ptest piped ctest output through 'sed -u', which busybox sed does
not support, so the pipeline produced no output and the ptest image
reported "ptests which had no test results: ['jsoncpp']".

Drop sed and classify ctest result lines in awk directly. This also
maps Timeout/Exception/Not Run results to FAIL; previously they were
printed as e.g. "Exception:: <name>" and ignored by the ptest parser.
