Fix CRMFPopClient on FIPS environment

When FIPS is enabled RSA key generation cannot have both temporary and
sensitive to false.

Since temporary is defined from a command option the sensitive is set to
null so the default for the environment will be used (true if FIPS is
enabled and false if FIPS is disabled).
