[PATCH v2] Improve externalsrc task dependency tracking

[Markus Lehtonen <markus.lehtonen@linux.intel.com>]

This refines the first version of the patch by utilizing (or abusing) inline
Python variable expansion: if the source tree is a git repository the python
function uses a custom git index file to track any changes in the source tree
and only returns this one index file for bitbake to hash. If the source tree is
not a git repository it works like the first version of this patch: all files
in the source tree are added as a task dependency (and thus hashed by bitbake).

[YOCTO #8853]
