Android: call eeClampMode 4 Exact, the name the other frontends use

The desktop and Big Picture pickers landed the same tier as Exact, and
GameIndex.md documents it under that name. Android was the only frontend
calling it something else, which made the same setting look like two
different ones depending on which screen the user was on.

The translation key moves with the label rather than keeping the old name
for a value it no longer matches, so the map stays alphabetical and there
is nothing left to mislead the next reader.
