pypi.bbclass: Set SRC_URI downloadfilename with an optional prefix

This allows avoiding clashes between source archives of a main
project and a pypi project using the same name and version.

The new optional setting is PYPI_ARCHIVE_NAME_PREFIX which is empty
by default so previous downloads can be used. Example usage:

PYPI_ARCHIVE_NAME_PREFIX = "pypi-"
