Add support for bonnell-xml package to p10ebmc_config

This commit adds the capability to pull files from the bonnell-xml repo
and build the bonnell system files as part of the p10ebmc_config.

However, the default setting is that the Bonnell system files will -NOT-
be built as part of the p10ebmc_config.
