Add an additional layer of inheritance for `aosp_shiba`,
`aosp_shiba_fullmte`, and `aosp_shiba_pgagnostic`.
This change adds a common layer of inheritance (shiba_generic.mk)
for non-factory products. This makes it easier to configure factory
and non-factory products differently.
Non-factory `shiba` products now inherits from
`device/google/shusky/shiba_generic.mk` which inherit from
`device/google/shusky/device-shiba.mk`.
