Accept application/pkcs7-mime to parse certificate. (letsencrypt#4797)

andygabby · web-flow · commit bf9b34cdf4bf · 2020-04-29T13:44:16.000-07:00
When downloading a pkcs7 file to parse for issuer, some servers
appear to deliver application/pkcs7-mime Content-Type and others
application/x-pkcs-mime. This patch changes the conditional
to look for both to invoke parseCMS().
