Testsuite: Fix fp-int-convert-timode-1.c testism.

The test fp-int-convert-timode-1.c uses FE_TONEAREST without
actually checking if the target has defined it.

Like the rest of the tests I now add a check to see if the target
has actually implemented it.

This fixed Arm newlib target failures.

Regtested on aarch64-none-elf and aarch64_be-none-elf and no issues.

Committed under the GCC obvious rules.

gcc/testsuite/ChangeLog:

	* gcc.dg/torture/fp-int-convert-timode-1.c: Add check for FE_TONEAREST.
