m68k: Wire up syscall_trace_enter/leave for m68k
m68k (other than Coldfire) uses syscall_trace for both trace entry
and trace exit. Seccomp support requires separate entry points for
trace entry and exit which are already provided for Coldfire.
Replace syscall_trace by syscall_trace_enter and syscall_trace_leave
in preparation for seccomp support.
No regression seen in testing with strace on ARAnyM.
