whitelist: Add new phosphor settings directories

The phosphor settings properties used to be stored under
/var/lib/obmc/ but they have moved to /var/lib/phosphor-*
directories.

Update the code update whitelist to include these
directories so that the settings properties and inventory
are preserved across code updates.

Closes openbmc/openbmc#3346

Tested: On Zaius, a PrepareForUpdate and an Apply preserve
the settings.
