[PATCH virt-viewer 3/3] Disable mnemonics via gtk-enable-mnemonics settings

[Marc-André Lureau <marcandre.lureau@xxxxxxxxx>]

This has 2 advantages, and I can't figure any drawback:
- it fixes the issue of mnemonic hints being draw when pressing Alt
  key (character underlined), even when they were disabled.
- it simplifies the code :)
