expat: Don't use getrandom() in the -native case
getrandom() is only available in glibc 2.25+ and uninative may relocate binaries onto systems that don't have this function. For now, force the code to the older codepath until we can come up with a better solution for this kind of issue. Signed-off-by: Richard Purdie <richard.purdie@linuxfoundation.org>

+The native version of expat may be used on older systems which dont have glibc 2.25
+and hence don't have getrandom() thanks to uninative. Disable the libc call and
+use the syscall instead to avoid a compatibility issue until we have 2.25 everywhere
+we support with uninative.
