[PATCH v2] BBFILES_DYNAMIC: add inverse mode

[PATCH v2] BBFILES_DYNAMIC: add inverse mode

[Konrad Weihmann]

Add an inverse mode for BBFILES_DYNAMIC.
Entries where the layername is prefix with '!' will act in inverted mode
including given glob mask in absence of the referenced layer.
This is useful to backfill recipes from potentially missing layer.
