Move w_lgamma_r to libm-compat-calls-auto
This patch adds the suffix "_compat" to lgamma_r wrappers and make
some adjustments to #includes and Makefiles. This is a step towards
deprecation of wrappers that use _LIB_VERSION / matherr /
__kernel_standard functionality.
Tested for powerpc64le, s390, and x86_64.

(libm-compat-calls-auto): Here.
