[gentoo-catalyst] [PATCH] create-iso.sh: split iso-level arguments

[Daniel Cordero <gentoo.catalyst@xxoo.ws>]

From: Daniel Cordero <catalyst@0xdc.io>

When enclosed in quotes and expanded with "${variable[@]}", the word is expanded
to be a single argument, rather than two separate arguments.

i.e. argv[2] = "-iso-level 3"
instead of
  argv[2] = "-iso-level"
  argv[3] = "3"

This lead to the failure:
  xorriso : FAILURE : -as mkisofs: Unrecognized option '-iso-level 3'
  xorriso : aborting : -abort_on 'FAILURE' encountered 'FAILURE'
  grub-mkrescue: error: `xorriso` invocation failed

This patch fixes commit 0b56dbe4d36c88b0b051d24451e15cd6b64c819d.
