tests: Generate the stub scripts using sed

Instead of trying to run ./test-conformance with the -l option to
generate a list of available tests it now runs sed on the
test-conform-main.c file instead. Running the generated executable is
a pain for cross-compiling so it would be nice to avoid it unless it's
absolutely necessary. Although you could tell people who are cross
compiling to just disable the conformance tests, this seems a shame
because they could still be useful along with the wrappers for example
if the cross compile is built to a shared network folder where the
tests can be run on the actual device.

The sed script is a little more ugly than it could be because it tries
to avoid using the GNU extensions '\+' and '\|'.

The script ends up placing restrictions on the format of the C file
because the tests must all be listed on one line each. There is now a
comment to explain this. Hopefully the trade off is worth it.
