[OE-core] [PATCH v2 1/1] scripts/contrib/bbvars.py: Rewrite to use tinfoil

Use tinfoil to collect all variable names globally and in each recipe.
This will capture more variable references than parsing manually.
With the use of tinfoil, this script can no longer distinguish unique
references to each variable, so it's no longer showing the count of
undocumented variables.
Removed the -m option since this script now searches through all recipes
in the configuration.
Fixes [YOCTO #2086]
