Fix GH-22280: Ignore non-finally try blocks

[prateekbhujel]

Fixes GH-22280.

zend_check_finally_breakout() checked every try/catch table entry as if it had a finally range. For a plain try/catch, finally_op is zero, so a goto emitted at opcode 0 could be treated as leaving a fake finally block.

Skip entries without a finally_op before checking finally jump boundaries.
