[kvm-unit-tests PATCH v3 1/1] runtime: indicate failure on crash/timeout/abort in TAP

[Nico Boehr <nrb@linux.ibm.com>]

When we have crashes, timeouts or aborts, there is currently no indication for
this in the TAP output. When all reports() up to this point succeeded, this
might result in a TAP file looking completely fine even though things went
terribly wrong.

For example, when I set the timeout for the diag288 test on s390x to 1 second,
it fails because it takes quite long, which is properly indicated in the
normal output:

$ ./run_tests.sh diag288
FAIL diag288 (timeout; duration=1s)

But, when I enable TAP output, I get this:

$ ./run_tests.sh -t diag288
TAP version 13
ok 1 - diag288: diag288: privileged: Program interrupt: expected(2) == received(2)
ok 2 - diag288: diag288: specification: uneven: Program interrupt: expected(6) == received(6)
ok 3 - diag288: diag288: specification: unsupported action: Program interrupt: expected(6) == received(6)
ok 4 - diag288: diag288: specification: unsupported function: Program interrupt: expected(6) == received(6)
ok 5 - diag288: diag288: specification: no init: Program interrupt: expected(6) == received(6)
ok 6 - diag288: diag288: specification: min timer: Program interrupt: expected(6) == received(6)
1..6

Which looks like a completely fine TAP file, but actually we ran into a timeout
and didn't even run all tests.

With this patch, we get an additional line at the end which properly shows
something went wrong:

not ok 7 - diag288: timeout; duration=1s
