[syslog-ng] 1.9.11 compile failure on Solaris 2.6/7

[Albert Chin]

Seems AF_INET6 is used unconditionally in src/cfg-grammar.y:
source_afsocket
        : KW_UNIX_DGRAM '(' source_afunix_dgram_params ')'      { $$ = $3; }
        | KW_UNIX_STREAM '(' source_afunix_stream_params ')'    { $$ = $3; }
        | KW_UDP { last_addr_family = AF_INET; } '(' source_afinet_udp_params ')
'               { $$ = $4; } 
        | KW_TCP { last_addr_family = AF_INET; } '(' source_afinet_tcp_params ')
'               { $$ = $4; } 
        | KW_UDP6 { last_addr_family = AF_INET6; } '(' source_afinet_udp_params 
')'             { $$ = $4; } 
        | KW_TCP6 { last_addr_family = AF_INET6; } '(' source_afinet_tcp_params 
')'             { $$ = $4; } 
        ;
