write: Always use verify_working_env()

Move the creation of secure_session and openssl-easyrsa.cnf (Temp)
to verify_working_env(). Create a session and temp-file in the temp-dir
EASRSA_TEMP_DIR, provided that the directory exists.

By default, EASYRSA_TEMP_DIR is set to the current PKI but that can be
decoupled and command 'write' can be run without a PKI, so long as a
valid temp-dir exists.

    * Always use here-doc version of openssl-easyrsa.cnf (2a8c0de)
      Only use here-doc if the current version is recognised by sha256 hash.
+     This will DELETE any default version of openssl-easyrsa.cnf
    * export-p12: New command option 'legacy'. OpenSSL V3 Only (f8514de)
      Fallback to encryption algorithm RC2_CBC or 3DES_CBC
