linux-user/m68k: remove simulator syscall interface

This interface has been introduced in 2005 with the
coldfire implementation (e6e5906b6e ColdFire target.)
and looks like to do what the linux-user interface already
does with the TRAP exception rather than the ILLEGAL
exception.

This interface has not been maintained since that.
The semi-hosting interface is not removed so coldfire kernel
with semi-hosting is always supported.
