Fix #2249

OpenSSL uses "sha1WithRSAEncryption" to represent 1.2.840.113549.1.1.5 and "sha1WithRSA" to represent 1.3.14.3.2.29. While 1.2.840.113549.1.1.5 is generally recognized as the "standard" OID for RSA with SHA-1 (see, for example, RFC 3279), 1.3.14.3.2.29 has been used in some places as well (https://codereview.chromium.org/1223763002, https://bugzilla.mozilla.org/show_bug.cgi?id=1042479, pyca/cryptography#3160)
