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.
