[OE-core] [PATCH] wic/bootimg-efi.py: add new source parameter "initrd_rename"

[Yongxin Liu]

When using initrd in bootloader configuration file, we may want
the name of initrd to be fixed. However, the actual name of initrd
may change and depend on distro/machine's name. "initrd_rename"
gives user a chance to rename initrd in final wic image.
