SCI: RAMA: Remove reminder beeping from arithmetic puzzles

ScummVM: 1.10.0git-5097-gd75dab4
Game: RAMA 1.0 DOS/English
Tester OS: Win7-64

When trying to solve the Bangkok building arithmetic puzzles the computer will beep about every 7-20 seconds while you are solving the same puzzle (it is waiting on your input). This is annoying. On faster systems it is about every 7 secs and on slower about every 20 seconds.

The machines make various beeping sounds when pushing buttons and when entering attempted solutions. I just want the beeping that happens for the reminders to stop.

Some of the harder puzzles can take more than a minute to solve so this will happen a lot and make concentrating harder.

This prompting behaviour is intentional and is thus outside the scope of any change in ScummVM.
