site: add xorg_cv_malloc0_returns_null
util-macros 1.18 will look in the autoconf cache for this value so instead of using overrides in xorg-lib-common, use the per-libc site cache. Alert readers may notice that the site file claims that glibc returns NULL from malloc(), when the previous change (e628c8aba0189de30de2833882b9999ff3b6547a) claimed that it didn't. The previous change was incorrect, whilst malloc(0) returns a valid pointer, realloc(p,0) does in fact return NULL, so the Xlib wrapper functions are needed.
