    Fix to use snprintf() instead of strlcpy() in pgproto.
    
    Commit 1f40c4fe7 modified pgproto to use strlcpy() to generate the v2
    protocol startup packet. Unfortunately strlcpy() is only available in
    glibc 2.38 or after, which is provided by Red Hat 10 or newer. Thus
    Red Hat 8 or 9 failed to build pgproto.
    
    This commit replaces strlcpy() with snprintf().
