Rearrange RNG code slightly
In preparation of exporting getentropy/getrandom to userspace, rearrange
code a bit:
- Define RtlGenRandom in ntdll.h.
- Drop calls to getentropy in favor of RtlGenRandom (fhandler_socket,
fhandler_dev_random).
- Add try/except blocks in fhandler_dev_random to return EFAULT rather
than crashing if buffer pointer is invalid.
