If we do create a libinux library, I'd definitely want getrandom(2) to
be defined as getrandom(), and not as sys_getrandom() or
linux_getrandom().

For bonus points we could also define a OpenBSD compatible
getentropy() interface so that programs that were already written to
use the OpenBSD interface (and perhaps have a configure test for it
already) would get the benefits of the getrandom(2) system call
immediately.
