KVM test: automate handling of cdkeys in unattended_install scripts

- Automatically replace cdkeys in unattended_install scripts.
  A dummy string (KVM_TEST_CDKEY) is replaced by an actual cdkey (normally
  defined in cdkeys.cfg) before installation begins.
- Make all Windows unattended scripts use the same dummy string.
- Add dummy cdkeys to cdkeys.cfg.sample, for WinVista, Win2008 and Win7.
  These must be replaced manually by the user.
