util.random: Test whether util.crand works before using it (fix #1734)
util.crand can be configured at compile time to use the Linux
getrandom() system call, available from Linux 3.17, but it is still
possible to load it with an older kernel lacking that system call, where
attempting to use it throws an ENOSYS error.
By testing for this on load we can fall back to /dev/urandom in this
case.
