disable (process) ebpf events when to many errors 
if an invalid opensnitch-procs.o module was loaded, we were flooding
the log with errors.
In these cases stop processing events after 20 errors (random, we should
have no errors).

This may occur if the module is malformed (valid .o ebpf module but
different structs, etc), or when loading modules from other versions.

Closes: #1099 #1082
