Lock RPC device after opening it.
Current design of the RPC protocol assumes that there is exactly one
client speaking directly to the HSM via the RPC channel, whether that
single client really is single or is a multiplexing daemon. PKCS #11
mutexes won't help here, so using flock(2) to grab an exclusive
"advisory" lock on the RPC file descriptor is the simplest solution.
