bitbake: cookerdata: Set TOPDIR when using bblayers.conf

Browse Source 
By definition, bblayers.conf is at the top of the build tree. We'd like
to support running bitbake anywhere within that build tree but TOPDIR
gets set to wherever cwd is. Change the code to reset TOPDIR
to the top of the build directory.

This shouldn't break anything but does make the system more usable.

(Bitbake rev: b266db27de0bba19a418e4d42e870649136b116b)
