bitbake: build: Allow deltask to take multiple tasknames

deltask currently supports only one task to delete but it would be useful
if it could support a variable which gets expanded to allow flexibility
in the metadata.

This is simple to support in bitbake and is how other directives such
as inherit operate so adjust the parser/code to handle that. It means
that syntax like:

EXTRA_NOPACKAGE_DELTASKS = ""
deltask ${EXTRA_NOPACKAGE_DELTASKS}

is now allowed.
