bitbake: bitbake-setup: capture revisions while checking out layers

When initializing a build setup from a conf.json that only sets 'rev'
to a tag or branch, the actual revision would not be captured or
logged.

To capture the current layer state after an 'init' or 'update', the
checkout_layers function is extended to store the revision the
bb.fetch.Fetch pulled, and write that information into a
sources-fixed-revisions.json file. This file can then be fed back into
bitbake-setup init as: --sources-overrides

This new 'sources-fixed-revisions.json' is written during 'update_build' and
stored alongside the 'config-upstream.json' in the config dir. And put
with the later under version control by calling 'commit_config" after
'update_build'.

The use of 'deepcopy' is necessary to not modify the original input
data - which python passes around as reference.
