[PATCH v2 06/15] KVM: selftests: Add a flag to print only test status in KVM Selftests run

[Vipin Sharma]

Add a command line argument, --print-status, to limit content printed on
terminal by default. When this flag is passed only print final status of
tests i.e. passed, failed, timed out, etc.

Example:
  python3 runner --test-dirs tests  --print-status
