Don't load non-UBI flash packages on UBI systems

Two un-needed applications are getting installed and started on
UBI enabled systems:

- download_manager.py (obmc-mgr-download.bb)
- bmc_update.py (obmc-flash-bmc.bb)

Remove these if it is a BMC UBI enabled system.

Moved all of the BMC flash logic to the phosphor layer where
it really belongs since the ability to update your OpenBMC
should come by default when bringing in phosphor.

Tested: Verified 2 python applications not present on witherspoon and
system boots and code updates fine. Verified romulus image still had
python applications and made it to Ready states.

Resolves openbmc/openbmc#2480
