Fix debug build's predefined-macros.txt (#407)

This commit fixes the ability to build `wasi-libc` with `-g` options and
possibly without `-O2` options as well. I've found this useful when
debugging issues as historically that the build fails when `-g` is
passed or optimizations are removed due to the checks against these
expectation files. This commit adds more filters to the list of macros
to ensure that optimization/debug related ones are all removed from the
expectation lists.
