docs: trusted-encrypted.rst: update parameters for command examples

The parameters in command examples for tpm2_createprimary and
tpm2_evictcontrol are outdated, people (like me) are not able to create
trusted key by these command examples.

This patch updates the parameters of command example tpm2_createprimary
and tpm2_evictcontrol in trusted-encrypted.rst. With Linux kernel v5.8
and tpm2-tools-4.1, people can create a trusted key by following the
examples in this document.
