actions: calculate password hash difficulty correctly
'fscrypt setup' is supposed to calibrate the Argon2 password hashing
difficulty to 1s by default, but actually it was setting it to only 1s /
num_cpus because the hashing is done with all CPUs and it is timed using
the CLOCK_PROCESS_CPUTIME_ID clock, which measures the time spent by all
threads in the process. Fix this by dividing the elapsed time by
HashingCosts.Parallelism, which is used as the number of threads.
