make sudo suggestions/help text 'sudo' aware

Binary package hint: powertop

By default, 'powertop' prints information such as:

  "PowerTOP needs to be run as root to collect enough information"

and:

  "echo 1500 > /proc/sys/vm/dirty_writeback_centisecs"

The first message can be changed to be more generic "root, or using 'sudo $0'". The second message can check $0 of the parent process and if being run via sudo display suggestions as:

  echo 1500 | sudo tee -a /proc/sys/vm/dirty_writeback_centisecs

Talking to Arjan (of the original authors), the language change could be done if the opinion for doing this would be strong enough, i.e. ovewcome the nuisance of having to get new translations. It seems translations are handled outside of the original authors' source trees.

In powertop.c (http://code.google.com/p/powertop/source/browse/trunk/powertop.c) there's a message when run without root capabilities.

901: if (geteuid() != 0)
902: printf(_("PowerTOP needs to be run as root to collect enough information\n"));

A change suggestion that would help beginner users:
      printf(_("PowerTOP must be run as root (sudo powertop) for full functionality\n"));

I am marking this bug as confirmed.
