Wire up installer, networking, and fix UEFI boot entry

- Dockerfile: compile and install orioninstall-gui + orioninstall script
- packages: add rsync, parted, arch-install-scripts, grub, efibootmgr,
  dosfstools, amd/intel-ucode, wpa_supplicant
- customize_airootfs.sh: enable NetworkManager + wpa_supplicant on boot
- orioninstall: fix UEFI (ESP at /boot, not /boot/efi); pass TIMEZONE
  and KEYBOARD into chroot heredoc; conditionalize microcode initrd lines
- menu: launch orioninstall-gui via pkexec (runs as root)
- profiledef: add file_permissions for installer binaries
