Phone: Update Polish translation

PS2: Added AOSP missing translation

Change-Id: Icf4b4ee53594cf341fc4f674bff6f88960a7fcf9
Phone: correct summary of national roaming [translation]

According to Android's writing guidelines for checkbox
settings [1], the summary should not reflect the state
of the checkbox setting but should describe the action
itself.

A workaround was applied earlier on, but this completely
removes the extra summary.
