metadata_scm.bbclass: Do not assume ${COREBASE} is a Git repo

The functions base_detect_revision() and base_detect_branch() try to
extract SCM meta information from the path returned by
base_get_scmbasepath(), which currently returns ${COREBASE}. However,
making the assumption that ${COREBASE} contains SCM meta information
can be false. It is true for Poky, but not necessarily other
environments. A better option is to look for the SCM meta information
based on the meta layer.

Since this works as expected for Git but not SVN, the call to
base_get_metadata_svn_revision() from base_detect_revision() was also
removed. This is not expected to affect anyone (partly based on the
comment in base_get_metadata_svn_revision()).
