[PATCH v2] wic: bootimg-efi: add label source parameter

[PATCH v2] wic: bootimg-efi: add label source parameter

[chee.yang.lee]

From: Chee Yang Lee <chee.yang.lee@intel.com>

Add new source parameter label to allow custom boot.conf/grub.cfg label,
so far it's hardcoded to "Boot".

Default label to "Boot" for systemd-boot and blank for grub-efi when source
parameter label are not set.
