Add new script download_and_build_qemu.sh that allows building QEMU from
sources. It installs all necessary packages to build QEMU from sources,
downloads QEMU sources and builds both x86_64 and aarch64 versions of
it.

I guess that's ok, but personally I prefer something simpler, like using "test -f /etc/redhat-release" or "test -f /etc/fedora-release" to check if this is a redhat-like system (including Fedora) and specifically fedora.

I personally prefer not to add the "-y". I think it's a good idea to allow the user, who has no idea that this script is even planning to install anything, say ok if anything needs to be installed.

Please use double quotes on $BUILD_DIR here an in most lines below. If the current directory's name has a space in it, all this code will break.
