Fix installation instructions for Debian/Ubuntu

There is no package called "qemu" here - thus use the two meta-packages
"qemu-system" and "qemu-user-static" instead.

While we're at it, add a note for people who might not need all
emulator binaries - in that case it makes sense to have a look
at the list of available packages first.
