perf script/python: Print array argument as string

With the Sebastian's change of handling num array argument (of raw
syscall enter), the script still failed to work like this:

  $ perf record -e raw_syscalls:* sleep 1
  $ perf script -g python
  $ perf script -s perf-script.py
  ...
  Traceback (most recent call last):
    File "perf-script.py", line 42, in raw_syscalls__sys_enter
      (id, args),
  TypeError: %u format: a number is required, not list
  Fatal Python error: problem in Python trace event handler
  Aborted (core dumped)

This is because the generated script tries to print the array arg as
unsigned integer (%u).  Since the python seems to convert arguments to
strings by default, just using %s solved the problem for me.
