random-util: allow RDRAND to be used in 32-bit x86 binaries
Rename rdrand64 to rdrand, and switch from uint64_t to unsigned long.
This produces code that will compile/assemble on both x86-64 and x86-32.
This could be useful when running a 32-bit copy of systemd on a modern
Intel processor.
RDRAND is inherently arch-specific, so relying on the compiler-defined
'long' type seems reasonable.
