Move w_exp to libm-compat-call-auto
This patch adds the "_compat" suffix to the wrappers of the function
exp, which use _LIB_VERSION / matherr / __kernel_standard
functionality.

Tested for powerpc64le, s390, and x86_64.

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

	* math/w_expl.c: Add suffix "_compat" to filename.
