Testsuite: Enable fp-int-convert-timode-1.c unconditionally when int128 supported.

This removes the call to fesetround as FE_TONEAREST
is the default and so the guard can be removed as well.

The test will then run as long as there's int128 support.

gcc/testsuite/ChangeLog:

	* gcc.dg/torture/fp-int-convert-timode-1.c: Always run if int128.
