  slides/sysdev-bootloaders-u-boot: improve "Installing U-Boot" slide

Felt awkward not to clearly mention we're talking about
internal storage. This slide comes from the old days when
you could brick a board by breaking its bootloader, and
couldn't recover by booting on external storage.

We could even remove this slide.
