Update iotop to latest HEAD checkout

Iotop on newer kernels is barely usable due to kernel.task_delayacct (CONFIG_TASK_DELAY_ACCT).
Update to the Factory version of iotop features the following changes:
* solves several UTF-8 issues
* switches to python3
* deal with kernel.task_delayacct (CONFIG_TASK_DELAY_ACCT)
* data.py get_cmdline: use errors=replace for unicode errors
