xorg-lib-common: fix malloc0returnsnull usage 

Xorg libraries that use Xmalloc need to know if malloc(0) returns NULL or not,
and as this is a runtime test it can't be checked for.  Previously
xorg-lib-common declared that malloc(0) did return NULL, but this isn't true for
eglibc (only uclibc).

Instead, use libc-specific overrides to pass the relevant option.

(ideally the check would use the autoconf cache so this can be stored in the site files)
