fix list of crypto devices for NetBSD, OpenBSD

[Bruno Haible]

The list of crypto devices in m4/gc-random.m4 is from 2006.

I get test failures of module 'getrandom' on current versions of
NetBSD and OpenBSD (NetBSD 7.0 and 9.0, and OpenBSD 6.5, to be precise).
These platforms have the quasi-standard /dev/random and /dev/urandom
meanwhile. No more /dev/srandom exists.

This patch fixes the test failures.
