selftests: Fix duplicated test number reporting

Commit 2964f6b ("selftests: Use ktap helpers for runner.sh") converted
the prints in runner.sh to use the relevant helpers from ktap_helpers.sh,
not modifying any of the strings printed in the process. This included
converting all the result reports to use the relevant ktap_test_ function.
Since the output was originally KTAP compliant the strings reported for
test names now include test numbers:

  ok 59 59 selftests: arm64: syscall-abi

instead of the expected format:

  ok 59 selftests: arm64: syscall-abi

which causes result parsers to interpret the second number as part of the
test name.

Given the use of the helpers the tracking of test numbers by runner.sh is
now redundant, remove it entirely to restore the expected output format.
