Subject: Split off test macros from ifa.tl into common file.

* Makefile (TESTS_OUT): Don't use find to hunt down tests;
but rather wildcard. This way common.tl is not mistakenly
identified as an independent test file.

* tests/012/ifa.tl: Removed test code, placed in new file
which is loaded.

* tests/common.tl: New file.
