dlls/kernel/console.c: Support PC speaker time/frequency on Linux

[David Lee Lambert]

Wine always beeps the same, if it beeps at all;  this patch starts to fix 
that.  The Linux console accepts codes so it can beep the PC speaker.  Now 
it might be easier to port programs that play little ditties...

Changelog:
  A better Beep() when Wine is run from the Linux console
