Up until now there are just two ways how to specify UEFI paths to
libvirt. The first one is editing qemu.conf, the other is editing
qemu_conf.c and recompile. Therefore, two new configure options
are invented: --with-default-loader --with-default-nvram.
At the same time, the list of default paths is extended to AAVMF.
which is an aarch64 port of OVMF.
