Use rhts-report-result alias instead of tmt-report-result for reporting beakerlib subresults

[seberm]

I was troubleshooting why the logs for beakerlib phases (aka tmt subresults) are not saved by tmt-report-result script and the reason is the following.

The beakerlib calls the command in BEAKERLIB_COMMAND_REPORT_RESULT variable in the following way:

$BEAKERLIB_COMMAND_REPORT_RESULT "$testname" "$result" "$logfile" "$score"

See the implementation of rlReport here:

• https://github.com/beakerlib/beakerlib/blob/5a85937f557b735f32996eb55cd6b9a33f3fe653/src/testing.sh#L1076

Suppose we use tmt-report-result as the value for BEAKERLIB_COMMAND_REPORT_RESULT (as a script name). In that case, the script will not be compatible with the third $logfile positional argument - it will just ignore it because it accepts the logfile provided only by the -o/--outputFile option by default.

We want to use the rhts-report-result alias because of a compatibility layer implemented by the tmt-report-result script itself. If the script gets called with rhts-report-result name, it will accept the third positional argument as a logfile:
