    lib/oe/copy_buildsystem: fix building eSDK with indirect paths in BBLAYERS
    
    Indirect paths (e.g. ${TOPDIR}/../meta-something) do generally work if
    used in BBLAYERS in bblayers.conf. However, if you built an extensible
    SDK with this configuration then the creation of the workspace within
    the SDK using devtool in do_populate_sdk_ext failed. This is because
    the copy_buildsystem code was no longer correctly recognising that the
    core layer ("meta") was part of a repository (e.g. openembedded-core /
    poky) that should be shipped together - because of the indirection - and
    thus it was splitting out the meta directory, and a number of places in
    the code assume that the meta directory is next to the scripts
    directory. Use os.path.abspath() to flatten out any indirections.
