gen_path_callouts: Looks for I2C_BUS_ALIAS

The I2C_BUS_ALIAS bus attribute holds the alias value the BMC uses for
I2C buses behind I2C muxes.  For example, a value of 30 could be an
alias for the bus on channel 3 of a mux on I2C bus 5.  This is the
actual value the BMC uses, so it doesn't need to be adjusted later
(subtract 1) like the other buses in the MRW require.

If this attribute is filled in for a device, use that value as the I2C
bus.
