bundle2._processpart: forcing lower-case compare is no longer necessary

Encoding whether or not a part is mandatory in the capitalization of the
parttype is unintuitive and error-prone.  This sequence of patches separates
these concerns in the API to reduce programmer error and pave the way for
a potential change in how this information is transmitted over the wire.

Since the parttype and mandatory bit are separated in bundle2.unbundlepart
(see previous patch), there is no longer a need to remove the mandatory bit
before working with the parttype.
