This patch adds following minor changes to prepare powertop
to support Android platform.

- add missing HAVE_CONFIG_H conditional check.
- remove un-used ethtool_cmd_speed_set and ethtool_cmd_speed
functions.
- minimize dependency on exception handling in catch blocks.

These changes will not affect powertop functionality.
