linux: Handle upower's UP_DEVICE_STATE_PENDING_CHARGE, PENDING_DISCHARGE

Browse Source 
On my laptop, the battery is configured to stop charging at around 80%
most of the time, to increase the overall useful lifetime of the battery.
When in that state, upower reports UP_DEVICE_STATE_PENDING_CHARGE
(numeric value 5), which SDL previously mapped to SDL_POWERSTATE_UNKNOWN.
This made the platform_testGetPowerInfo automated test fail, because
it assumes that SDL_POWERSTATE_UNKNOWN means no battery is connected,
and does not expect to see a percentage.

Map UP_DEVICE_STATE_PENDING_CHARGE (5) to SDL_POWERSTATE_CHARGED, which
seems close enough.

Also map UP_DEVICE_STATE_PENDING_DISCHARGE (6) to
SDL_POWERSTATE_ON_BATTERY, which matches how at least GNOME presents it.
