bitbake: build: Add clean_stamp API function to allow removal of task stamps

Browse Source 
We currently have no API to be able to remove all the potential stamps of a
task. It is unusual to need to do this, particularly as you could race against
other things happening in the system but we do have a use case for this in
cleaning up sysroots in OE-Core. The alternative is to mess with CLEANMASK in
OE-Core but that is just going to add potential for errors.

We need the first part of the make_stamp() function so separate that out so
it can be called seperately.
