Remove generated zend_jit_x86.c on make clean

Not removing this causes build failure when reconfiguring and rebuilding after a `make clean`, e.g. enabling/disabling ZTS.

This makes https://bugs.php.net/bug.php?id=80561 more bearable. Ideally it would be rebuilt automatically on configuration change if necessary, but I have no idea how to implement this.

Closes GH-6702.
