    scripts/wic: explicitly set BUILDDIR within eSDK
    
    When we run wic within eSDK:
    $ wic create mkefidisk -e core-image-minimal
    
    ERROR: BUILDDIR not found, exiting. (Did you forget to source oe-init-build-env?)
    
    In order to figure out variable values, one must have sourced
    the OE build environment setup script. However, when we are in
    within the eSDK environment which isn't initialised like the
    normal OE build environment, we can't use wic utility with eSDK.
    
    Reference:
    https://www.yoctoproject.org/docs/latest/mega-manual/mega-manual.html#wic-requirements
    
    While wic ought to be fixed to be able to run without bitbake
    & native tools [YOCTO #11281], but this is a workaround to set
    BUILDDIR in the environment so that bitbake environment is setup
    for wic to build its required native tools.
