scripts: Remove check-qerror.sh

qerror.h contains leftovers from the now-defunct QError API.

There's only a handful of string macros left, and no one is supposed
to add anything else. The check-qerror.sh script was used to make sure
that all definitions on the qerror.c and qerror.h files were sorted
alphabetically. The former was removed three years ago, and the latter
is now in a different location, so the script doesn't even work (as
a matter of fact the alphabetical order was broken last time someone
added a macro -also in 2015- and no one seemed to notice).

There's no point in fixing this script so let's just remove it.
The rogue macro is also moved to its correct location.
