As motivation for this; we have had two breakouts of dib in recent
memory. One was a failure to unmount through symlinks in the core
code (I335316019ef948758392b03e91f9869102a472b9) and the other was
removing host keys on the build-system
(Ib01d71ff9415a0ae04d963f6e380aab9ac2260ce).
For the most part, dib runs unprivileged. Bits of the core code are
hopefully well tested (modulo bugs like the first one!). We give free
reign inside the chroot (although there is still some potential there
for adverse external affects via bind mounts). Where we could be a
bit safer (and could have prevented at least the second of these
breakouts) is with some better checking that the "sudo" calls
*outside* the chroot at least looked sane.
This adds a basic check that we're using chroot or image paths when
calling sudo in those parts of elements that run *outside* the chroot.
Various files are updated to accomodate this check; mostly by just
ignoring it for existing code (I have not audited these calls).
Nobody is pretending this type of checking makes dib magically safe,
or removes the issues with it needing to do things as root during the
build. But this can help find egregious errors like the key removal.

The bootloader element lacks the mapping for grub-pc and extlinux
This adds it.

Our bootloader install fails on non-gentoo builds due to missing pkg-map
for grub-pc. This map should really live in the bootloader element, so
move it there and fill it out.

In order to add more flexibility to the vm and bootloader
elements, split the functionality in two different ones, and
make vm depend on bootloader element.
This will allow to construct more elements that depend on
bootloader, and develop both elements independently.
