[OE-core] [PATCH 11/17] wic: deferred call of hlp.get_wic_plugins_help()

[Ed Bartosh]

If get_wic_plugins_help is called from wic main module
it calls git_bitbake_var at some point. This fails when
wic is called from bitbake as 'bitbake -e' can't be
run.

Moved call of this method to help.py in order to call it
later, when BitbakeVariables singleton is properly initialized
to get variables from .env files.
