ovs-pki: Use SHA-512 instead of SHA-1 as message digest.

Browse Source 
The upcoming OpenSSL 1.1.0 release disables use of SHA-1, which breaks the
OVS unit tests, which use SHA-1.  We last tried to switch to SHA-512 in
2014 with commit 9ff33ca75e9fcc ("ovs-pki: Use SHA-512 instead of MD5 as
message digest."), but we had to downgrade to SHA-1 in commit 4a1f9610682d
("ovs-pki: Use SHA-1 instead of SHA-512 as message digest.") because
XenServer did not support SHA-512.  It has been a few years, so let's try
again.
