Adopted ternary LFS3_IFYES_* macros

This is hopefully a better alternative to LFS3_IFDEF_YES_* macros.

If we need special behavior for LFS3_IFDEF_YES_*, we almost always need
special behavior for LFS3_IFDEF_NO_* and LFS3_IFDEF_MAYBE_* as well.

So merging all three states into a single macro saves typing and
hopefully encourages correct handling of all cases.

No code changes.
