x86_64: Fix missing wcsncat function definition without multiarch (x86-64-v4)
This code expects the WCSCAT preprocessor macro to be predefined in case
the evex implementation of the function should be defined with a name
different from __wcsncat_evex. However, when glibc is built for
x86-64-v4 without multiarch support, sysdeps/x86_64/wcsncat.S defines
WCSNCAT variable instead of WCSCAT to build it as wcsncat. Rename the
variable to WCSNCAT, as it is actually a better naming choice for the
variable in this case.
