[FM] #lqa5f0cf83f: Android - LQA - MR1 Radio and Dual SIM - RU - Discard button truncated

In the saving the recording dialog box the "Discard" button is
truncated to 2 (two) letters. Currently we use the most obvious
and explicit translation of ".. .........". This can be shortened,
if required, but not to 2 letters anyway. Please provide more space.

The fix is to change the layout.
