[2.23 COMMITTED] tst-audit10: Fix compilation on compilers without bit_AVX512F [BZ #19860]

[Florian Weimer]

	[BZ# 19860]
	* sysdeps/x86_64/tst-audit10.c (avx512_enabled): Always return
	zero if the compiler does not provide the AVX512F bit.

(cherry picked from commit f327f5b47be57bc05a4077344b381016c1bb2c11)
