[CRIU] [PATCH 2/2][v3] zdtm.py: add support of test reports in TAP format

[Sergey Bronnikov]

Usually we run CRIU tests automatically using Jenkins CI and it reports status
as PASS/FAIL for overall testsuite on used environment. You should dig into log
files to figure out how many tests were failed and skipped. This patch brings
support of cute reports in TAP (Test Anything Protocol) format.

The sample of report:

TAP version 13
1..242
ok 1 - conntracks # SKIP manual run only
ok 2 - busyloop00
ok 3 - sleeping00
ok 4 - pid00
ok 5 - caps00
ok 6 - wait00

NOTE: report will be generated only when options --keep-going and --report
are specified.
