cr50: reduce TRNG use during RSA prime checkstabilize-14438.B-cr50_stab
It seems we have relatively high number of devices with slow TRNG,
mostly Octopus and Grunt platforms. To mitigate potential issues reduce
load on TRNG during witness generation in prime number check, relying
on already generated random from DRBG.
BUG=b:211648605
TEST=test/tpm_test/tpm_test.py - checking RSA key gen and that
deterministic key gen is not affected.
