Move detailed version info to first line of --version output

Change --version output format to show all build information on the first line:
memtier_benchmark v=255.255.255 sha=8985eb5a:1 bits=64 libevent=2.1.12-stable openssl=OpenSSL 3.0.13 30 Jan 2024

This makes it easier to parse and matches the Redis version output style.
