There's enough instances of SSTATEPOSTINSTFUNCS dotted around even just
oe-core, but they're all going to be using SSTATE_INSTDIR as the working
directory.  Whilst you have a valid point that the functions should respect
[dirs] if set, for the case of sstate post-install hooks I think we should
just force the right path so the recipe creators don't have to worry about
this.
