ArmVirtPkg/PlatformBootManagerLib: connect Virtio RNG devices again

Browse Source 
Virtio RNG devices are never boot devices, so in commit ff1d0fbfba we
stopped connecting them. This is a problem because an OS boot loader may
depend on EFI_RNG_PROTOCOL to seed the OS's RNG.

Connect Virtio RNG devices again. And, while commit ff1d0fbfba removed
that from PlatformBootManagerAfterConsole(), reintroduce it now to
PlatformBootManagerBeforeConsole() -- this way Driver#### options launched
between both functions may access EFI_RNG_PROTOCOL too.
