PSR2/PSR12/ControlStructureSpacing: don't listen for T_ELSE

No functional changes.

These sniffs only concerns themselves with control structures which take parentheses, so listening for `T_ELSE` is unnecessary as the sniffs will never do anything for that token (they each bow out on no 'parenthesis_opener'/'parenthesis_closer' found).
