rng-tools: increase initialization robustness together with jitterentropy-3.4.1

With jitterentropy 3.4.1 the initial timeout of rng-tools for the
initialization of jitterentropy seems to be too small in some cases.
Set a larger timeout for tests. Add comment how this timeout can be
set by users needing it.

# After updating to jitterentropy 3.4.1 jitterentropy initialization seams

# jitterentropy entropy source. You can increase the init timeout with a command-line
# option (-O jitter:timeout:SECONDS). The environment variable above only has effect
# for the test cases.
# Patching the timeout to a larger value was declined upstream,
