oracle: fix detect_openstack to report True on OracleCloud.com DMI data

The OpenStack datasource in 18.3 changed to detect data in the
init-local stage instead of init-network and attempted to redetect
OpenStackLocal datasource on Oracle across reboots. The function
detect_openstack was added to quickly detect whether a platform is
OpenStack based on dmi product_name or chassis_asset_tag and it was
a bit too strict for Oracle in checking for 'OpenStack Nova'/'Compute'
DMI product_name.

Oracle's DMI product_name reports 'SAtandard PC (i440FX + PIIX, 1996)'
and DMI chassis_asset_tag is 'OracleCloud.com'.

detect_openstack function now adds 'OracleCloud.com' as a supported value
'OracleCloud.com' to valid chassis-asset-tags for the OpenStack
datasource.
