Subject: [PATCH] bridge/vlan.c: bridge/vlan.c: fix build with gcc 14 on musl
 systems

On glibc based systems the definition of 'struct timeval' is pulled in
with inclusion of <stdlib.h> header, but on musl based systems it
doesn't work this way.  Missing definition triggers an
incompatible-pointer-types error with gcc 14 (warning on previous
versions of gcc):

../include/json_print.h:80:30: warning: 'struct timeval' declared inside parameter list will not be visible outside of this definition or declaration
   80 | _PRINT_FUNC(tv, const struct timeval *)
