ext/opcache/zend_jit: call TSRM dtor before unloading opcache.so

Commit a211956 added a TSRM destructor, but that destructor
will get called by tsrm_shutdown(), which is after opcache.so has
already been unloaded, resulting in a shutdown crash, e.g.:

  #0  0x00007fad01737500 in ?? ()
  php#1  0x000055ac54e723c4 in tsrm_shutdown () at TSRM/TSRM.c:194
  php#2  0x000055ac54c42180 in main (argc=80, argv=0x55ac57bc14d0) at sapi/cli/php_cli.c:1388

By calling ts_free_id() before opcache.so gets unloaded, we can easily
fix this crash bug.
