crt: test: Add t_excpt_int_divzero

Check that the integer division by zero throws EXCEPTION_INT_DIVIDE_BY_ZERO
SEH exception and catch it via XFAIL_TESTS.

Because handling of exceptions for main thread is different than for
threads spawned by CRT _beginthreadex() function, add also test via
_beginthreadex() function.
