[OE-core] [PATCH 2/2] wic: Allow to use a custom config for bootloaders

From: Mariano Lopez <mariano.lopez at linux.intel.com>

This change will allow to use a user defined file as the
configuration for the bootloaders (grub, gummiboot, syslinux).

The config file is defined in the wks file with the "configfile"
option in the bootloader line.

[YOCTO #8003]
