[yocto] [layerindex-web] [PATCH 2/3] update.py: Allow bitbake to live in a subdirectory of a repository

[Mark Hatle]

Add a new BITBAKE_PATH to the settings file to specify the path within the
BITBAKE_REPO_URL where bitbake lives.  This is useful when using a combined
repository, such as poky, that contains bitbake, openembedded-core and other
layers.

This change also changes the default path, in the fetch directory, for the
bitbake checkout.  It no longer uses the path 'bitbake', but instead uses the
same URL processing as the layer fetching.

There is a side effect that, when using a shared fetch, the branch of the
layer will be used instead of the specified bitbake branch.  Generally this
is a reasonable compromise, since in a combined repository bitbake and
openembedded-core component should already match.
