bitbake: BBHandler: Drop cwd from search path 

Whilst bitbake has done this for a long time, the behaviour of resolving
class files against cwd is not desirable. This can be seen during
base configuration parsing when looking for base.bbclass where a dependency
on cwd is added. If cwd then changes, the cache is invalid and triggers a
re-parse.

The only real option is to drop this entry and if files can't be found, we
fix BBPATH in the cases where it needs fixing. I didn't find any in the
random selection of layers I tested parsing locally.

(Bitbake rev: 508aad9d5db7e51328b1fd6ee53b4bc3720a30b7)
