Fix tests for complex overloads of std::arg and std::proj

The test for the synopsis of <complex> incorrectly adds constexpr to
two functions in C++2a mode, but the C++2a draft and the <complex>
header do not declare them constexpr.

	* testsuite/26_numerics/headers/complex/synopsis.cc: Remove incorrect
	constexpr specifiers from arg and proj.
