Fedora supports TLS down to 1.0 in LEGACY crypto-policy, but TLS 1.0
defaults to rsa_pkcs1_md5_sha1 with RSA certificates by default.
However, MD5-SHA1 would require SECLEVEL=0, because its 67 bits of
security do not meet SECLEVEL=1's requirement of 80 bits.
Instead of setting SECLEVEL to 0 in the LEGACY crypto-policy (which
would include all algorithms, regardless of their security level), allow
MD5-SHA1 if rh-allow-sha1-signatures is yes and SECLEVEL is 1.
Additionally, fix a regression in evp_pkey_name2type caused by the tr_TR
locale fix.
