getrandom: add helper for getrandom() syscall

getrandom() was introduced in version 3.17 of the Linux kernel.
By default getrandom() block until /dev/urandom pool has been initialized
and then read from it.
Read buffer is 256 bytes so getrandom() calls always succeed.

First usage will be to save a seed for /dev/urandom.
