insane.bbclass: simplify exceptions for 32 bit time API check

Existing implementation required to list both specific problematic apis, and files that
use them: neither is necessary as both are seen in package_qa error messages, and
can cause excessive amount of exception lines, if there are too many files, or
they are installed in arch-specific locations. Also, the value of INSANE_SKIP
should be the test that needs to be skipped, and in this case it wasn't.

Also, all problematic recipes are now correctly listed.
