Use libm_alias_ldouble in sysdeps/x86_64/fpu.

This patch continues the preparation for additional _FloatN / _FloatNx
function aliases by using libm_alias_ldouble for sysdeps/x86_64/fpu
long double functions, so that they can have _Float64x aliases added
in future.

Tested for x86_64, including build-many-glibcs.py tests that installed
stripped shared libraries are unchanged by the patch.
