Remove regression-qemu.sh

closes #320

Ok, I am not a huge fan of such solution.
Ideally, we simply execute the regression.sh as we do for any other platform, and only the required tests are executed, thanks to the correctly set test flags.

That would be the goal towards resolving the linked issue.

[PLangowski]

Isn't this what happens in this script? If we set CONFIG to qemu, only some of the tests are executed (the ones that were listed in regression-qemu.sh, so I assume those can run on QEMU)

@PLangowski But this should be resolved by properly setting support flags in platform-configs/qemu.robot, not be the if-else here. This MR should require no modifications to regression.sh script whatsoever.

@PLangowski You pushed some WIP commit in July, do you intend to finalize this at some point? Do you know how?

[PLangowski]

@macpijan I got stuck here. For some reason RF fails to establish a serial connection over telnet when running regression.sh on qemu. The problem does not occur when I run the tests separately.
dasharo-compatibility_log.txt

@PLangowski Well, if we look in the log, the obvious difference is the addition of

when running the whole regression.

This comes from the dasharo-compatibility/__init__.robot. You should find answer there.

[PLangowski]

Yes, but I have modified it to only run Prepare Test Suite, which works when running single test files. When comparing run.sh vs single test file logs, I couldn't find any difference except for the failing telnet keyword. I might have missed something.
