externalsrc.bbclass: Add task buildclean 

The buildclean task should call the package build system clean
command, just implemented for Make for now.

This is meant for recipes where S == B, but can be useful as a
standalone task for other recipes too.

When S == B, set it to run before do_clean which will do what most
developers expect when calling bitbake -c clean.  For S != B, do not
add it before clean as it is not needed and may take some time.

(From OE-Core rev: cfaad320d9565003e97893efcb14d00d0b8e23bb)
