Handle the conditional decoding of execve() argument and environment

arrays generically rather than duplicating a hack in all of the backends.
- Add two new system call argument types and use them instead of StringArray
  for the argument and environment arguments execve and linux_execve.
- Honor the -a/-e flags in the handling of these new types.
- Instead of printing "<missing argument>" when the decoding is disabled,
  print the raw pointer value.
