EST: Write the RSA private key using the standard PRIVATE KEY format

The routines used for using raw RSA keys directly have been deprecated
in OpenSSL 3.0. There should be no particular need to use the "RSA
PRIVATE KEY" format, so replace this with the more common "PRIVATE KEY"
format that can be written without use of the deprecated functions.
