[C99] Remove entry for LIA compatibility

We previously marked this as "No" but that's confusing; Annex H doesn't
require any changes for a C implementation, it's about how C relates to
other standards. We could mark this N/A, but I think it makes more
sense to treat it like a runtime library-specific change and simply
remove it from the tracker entirely.
