fix(deploy): make live ISOs USB-bootable (isoImage.makeUsbBootable)

Browse source 
The live ISO config set makeEfiBootable + makeBiosBootable but omitted
makeUsbBootable, so the image got BIOS+UEFI El Torito boot catalogs but
no isohybrid MBR/GPT — i.e. no partition table. dd'd to a USB stick it
shows iso9660 on the whole device with no ESP, and picky firmware (the
Sintra's Aaeon UP Board) won't recognise it as bootable, falling back to
its android-ia entry. Enabling makeUsbBootable applies the isohybrid MBR
(isohdpfx.bin) + GPT/ESP. Fixes USB boot for every model's live ISO.
