[OE-core] [PATCHv2 0/1] Improve how to determine METADATA_REVISION

We noticed that METADATA_REVISION was always set to '<unknown>' in our
builds. It turned out that this was because the code in
metadata_scm.bbclass that sets it assumed that ${COREBASE} contains a
repository. This may be true when working with Poky, but is not
necessarily true for other setups. E.g., in our setup we clone Poky,
OpenEmbedded and other repositories using the repo tool and then
create symbolic links from the base directory to the parts that we
want. Since ${COREBASE} is defined based on the path to the meta
layer, it should be a better option to use ${COREBASE}/meta when
looking for the SCM meta information.

Since this works as expected for Git but not SVN, I removed the option
to call base_get_metadata_svn_revision() from
base_detect_revision(). I doubt this should affect anyone (partly
based on the comment in base_get_metadata_svn_revision()), but if this
is not acceptable, it should be trivial to change the code so the meta
directory is only used when looking for Git meta information. However,
since it would require the introduction of two functions to wrap the
Git functions, I refrained from this option until requested otherwise.

PATCHv2: Added note about the removed call to
base_get_metadata_svn_revision() to the commit message.
