Looks like gitlab doesn't have write access to system.temp_dir

Just write to whatever dir, maybe that'll work.

exec/tests/crypt/cryptkeyset.js

-var ks = CryptKeyset(system.temp_dir + "tmpkeyset", CryptKeyset.KEYOPT.CREATE);
+var ks = CryptKeyset("tmpkeyset", CryptKeyset.KEYOPT.CREATE);
 ks.close();
-file_remove(system.temp_dir + "tmpkeyset");
+file_remove("tmpkeyset");
