pgsql: Convert encrypted SSL test keys to PKCS#8 format

Convert encrypted SSL test keys to PKCS#8 format

OpenSSL in FIPS mode rejects several encrypted private keys used in
the test suites ssl and ssl_passphrase_callback. This is because they
are in a "traditional" OpenSSL format that uses MD5 for key
generation. The fix is to convert them to the more standard PKCS#8
format that uses SHA1 for key derivation.

This commit contains the converted keys, with the conversion done like
this:

openssl pkcs8 -topk8 -in src/test/modules/ssl_passphrase_callback/server.key -passin pass:FooBaR1 -out src/test/modules/ssl_passphrase_callback/server.key.new -passout pass:FooBaR1
mv src/test/modules/ssl_passphrase_callback/server.key.new src/test/modules/ssl_passphrase_callback/server.key

etc., as well as updated build rules to generate the keys in the new
format if they need to be regenerated.
