kcsan: avoid passing -g for test
commit 5eb39cde1e2487ba5ec1802dc5e58a77e700d99e upstream.
Nathan reported that when building with GNU as and a version of clang that
defaults to DWARF5, the assembler will complain with:
Error: non-constant .uleb128 is not supported
This is because `-g` defaults to the compiler debug info default. If the
assembler does not support some of the directives used, the above errors
occur. To fix, remove the explicit passing of `-g`.
All the test wants is that stack traces print valid function names, and
debug info is not required for that. (I currently cannot recall why I
added the explicit `-g`.)
