[committed] testsuite: d: Adjust test for d_runtime_has_std_library

[Iain Buclaw]

Hi,

This patch adjusts the test for the D std library so that it doesn't
incorrectly return true on targets --with-libphobos-druntime-only=yes.

The function cos() is treated as an intrinsic, so always exists.

Regtested with --enable-libphobos --with-libphobos-druntime-only=yes.

Committed to mainline.

Regards,
Iain.
