Details:

Because it uses sys_timeout() directly, igmp_tick() will not work with
NO_SYS=1 since for this, sys_timeout() is defined to nothing.

I propose to just remove the sys_timeout() call from igmp_tick() and instead
including a comment that this function has to be called every x
milliseconds.

Then, I would create a wrapper function in tcpip.c for those who use netconn
or socket API and create the timer in tcpip_init() (like for all the other
timers). This way, one can call igmp_init() from anyywhere (e.g.
initialization before OS starts), also, which resembles the init scheme for
the other modules.
