slirp: Fix build with gcc 9
Build fails with gcc 9: CC slirp/ndp_table.o slirp/ndp_table.c: In function ‘ndp_table_add’: slirp/ndp_table.c:31:23: error: taking address of packed member of ‘struct ndpentry’ may result in an unaligned pointer value [-Werror=address-of-packed-member] 31 | if (in6_equal(&ndp_table->table[i].ip_addr, &ip_addr)) { | ^~~~~~~~~~~~~~~~~~~~~~~~~~~~ slirp/ndp_table.c: In function ‘ndp_table_search’: slirp/ndp_table.c:75:23: error: taking address of packed member of ‘struct ndpentry’ may result in an unaligned pointer value [-Werror=address-of-packed-member] 75 | if (in6_equal(&ndp_table->table[i].ip_addr, &ip_addr)) { | ^~~~~~~~~~~~~~~~~~~~~~~~~~~~ cc1: all warnings being treated as errors The ndpentry structure isn't used to model on-the-wire data or anything else that would care for the struct layout. It doesn't need to be packed actually. Just drop SLIRP_PACKED.
