pinguybuilder: make BIOS and EFI boot menus consistent

[dougburks]

When booting a UEFI box, choosing the "Install" option results in "Installer crashed". For 16.04.4.2, we need to remove the "Install" option from UEFI boot menu.

In the meantime, folks can choose "Try SecurityOnion 16.04.4.1 without installing" (the default option) to boot into the Live Desktop and then double-click the installer.

/usr/lib/PinguyBuilder/boot/grub/grub.cfg - change first entry to Boot and remove second entry

/etc/PinguyBuilder/isolinux/isolinux.cfg.vesamenu - change first entry to Boot
