Remove system_server_current related work arounds

(cherry picked from db3ad82810879ba236946259867af66fdb017fc1)

Previously, a library that set sdk_version: "system_server_current"
could only access system-server or public APIs from other libraries.
After change r.android.com/2238635 they will be able to access the
following (in order):
* system-server
* module-lib
* system
* public

Bug: 204176972
Test: m com.android.tethering
      # Without change r.android.com/2238635 the affected libraries
      # fail to compile due to missing symbols that are not in the
      # public API. With that change it compiles correctly.
