[RFC PATCH 03/10] wic-img: Satisfy the quirks of latest wic

[Vijai Kumar K <Vijaikumar_Kanagarajan@mentor.com>]

The latest WIC doesnot use fakeroot if pseudo_dir(IMAGE_ROOTFS/../pseudo)
is non-existent. This results in wic_fakeroot not being used. Create a
dummy pseudo_dir to satisfy wic.

WIC hardcodes the python(/usr/bin/python3-native/python3) to be used
while running bmaptool. The above path is OE specific and hence breaks
build in ISAR. Create a symbolic link in the above location to satisfy
wic.
