initrdscripts: init-install-efi.sh install extra files for ESP
Currently the install script copy only few hard coded item while
setting up target ESP, kernel artifacts, all .efi in EFI/BOOT,
grub & boot cfg and loader.conf.
While ESP can be much complex, eg: contain multiple initrd.
Add a ESP folder to carry any other files to setup onto ESP.
