[PATCH] umdns: fix compilation with GCC 10

[Rosen Penev]

The previous fix seems to not be enough.

/service.c:242:10: error: 'strncpy' offset 6 from the object at 'b' is
out of the bounds of referenced subobject 'name' with type 'uint8_t[]'
 {aka 'unsigned char[]'} at offset 6 [-Werror=array-bounds]
242 | s->id = strncpy(d_id, blobmsg_name(b), n);
