Fix bits/math-finite.h exp10 condition (bug 22082).

bits/math-finite.h handles exp10 if __USE_GNU.  It should use the
condition __GLIBC_USE (IEC_60559_FUNCS_EXT), as in bits/mathcalls.h.
This patch fixes the condition.

Tested for x86_64.

	[BZ #22082]
	* math/bits/math-finite.h (exp10): Redirect if [__GLIBC_USE
	(IEC_60559_FUNCS_EXT)], not [__USE_GNU].
