Remove pulling BiosID for the system schema

This is causing 500 errors on POWER platforms, given that (shocker) they
don't have a BIOS!  In practice, this isn't even the right way to grab
the version information, we should be grabbing it over the software
version interface https://github.com/openbmc/phosphor-dbus-interfaces
/blob/master/xyz/openbmc_project/Software/Version.interface.yaml
