scripts/wic: append bitbake executable file path in eSDK environment

wic needs a set of tools to be available from sysroots.
wic will find bitbake executable within the environment,
and wic was unable to locate bitbake executable within eSDK
because it wasn't setup with the OE build environment script.
Hence, we need to add bitbake file path into the environment
PATH for wic to be able to discover it and import bb modules.
