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.

	* math/Makefile (libm-calls): Move w_lgammaF_r...
	(libm-compat-calls-auto): Here.

	* math/w_lgamma_r.c: Add suffix "_compat" to filename.
	* math/w_lgammaf_r.c: Likewise.
	* math/w_lgammal_r.c: Likewise.
