Allow SHA1 usage in HMAC in TLS

The EVP_DigestSign API is used in TLS to compute a SHA1 HMAC, which is
OK from our point of view, but was blocked so far. Modify
0049-Selectively-disallow-SHA1-signatures.patch to check the EVP_PKEY
type for HMAC (and TLS1-PRF and HKDF), and allow SHA1 for these cases.

Note that TLS1.1 signs a MD5-SHA1 hash with a private key, which does
not work with rh-allow-sha1-signatures = no, so the minimum TLS version
will be TLS 1.2.
