expr: Remove evalexpr() and just use condexpr() with eval()

evalexpr() was originally named `constexpr`, since it matched the
constant-expression rule in the grammar. It had to be renamed due
to conflict with the C23 constexpr keyword.

However, since 2e3ecc70, eval has just one argument, so just call
eval(condexpr()) directly.
