Instead of building a script on the fly (which just repeats the same thing for each test collection), move the script out of the Makefile and into run_kselftest.sh, which reads kselftest-list.txt.
Adjust the emit_tests target to report each test on a separate line so that test running tools (e.g. LAVA) can easily remove individual tests (for example, as seen in [1]).
