libstdc++: Remove unnecessary dg-options and outdated comment

It's no longer true that 1.0if has type float _Complex when GNU
extensions are enabled, so remove the hardcoded -std option.

libstdc++-v3/ChangeLog:

	* testsuite/26_numerics/complex/literals/types.cc: Remove
	dg-options and add target selector instead.
