Commit ee5d0f89de3e53cdb0dc added range checking on reboot-timeout
to only allow the range 0..65535; however both qemu and libvirt document
the special value -1 to mean don't reboot.
Allow it again.
Fixes: ee5d0f89de3e53cdb0dc ("fw_cfg: Fix -boot reboot-timeout error checking")

The special value -1 means "don't reboot" for QEMU/libvirt.
Add a trivial test.
