Fix host path for dexpreopted system server modules defined in Make. 

Previously there was a discrepancy between the generated paths for
Soong modules that used "out/soong/system_server_jars" and Make modules
that used "out/system_server_jars". This happened because the default
output directory is $OUT/soong for the normal Soong config and jsut $OUT
for the reduced "null config" created by dexpreopt_gen.

As a result, class loader context for system server jars defined in Make
was referring to nonexistent jars, which caused non-fatal dex2oat errors
(the build was not broken, so the errors remained unnoticed):

  Failed to determine oat file name for dex location out/system_server_dexjars/[...]
  Could not open dex files from location: out/system_server_dexjars/[...]

Test: aosp_walleye-userdebug boots
Test: cherry-picked in master-arc-dev that has a Make system server jar
  arc-services, `lunch lunch cheets_x86-userdebug && m`, check that the
  generated dexpreopt.sh for arc-services contains paths starting with
  "out/soong/system_server_jars" rather than "out/system_server_jars".
