master b64d04c: Fix gpg2-related test failures on RHEL 7.8

[Paul Eggert]

branch: master
commit b64d04c3d63d009ffeb801a128a39e3728ff9a99
Author: Paul Eggert <eggert@cs.ucla.edu>
Commit: Paul Eggert <eggert@cs.ucla.edu>

    Fix gpg2-related test failures on RHEL 7.8
    
    * test/lisp/gnus/mml-sec-tests.el (test-conf)
    (mml-secure-en-decrypt-passphrase-no-cache-openpgp-todo)
    (mml-secure-run-tests-with-gpg2):
    Use epg-find-configuration instead of the obsolescent
    epg-configuration.  This fixes test failures on RHEL 7.8,
    where ‘gpg’ and ‘gpg2’ are both 2.0.22.
