SdkLibraryImport's DexJarInstallPath uses installPath from source module

Even though actual installed module path is the same as source module,
it uses impl's one.

Bug: 188179858
Bug: 193082464
Test: compare dexpreopt_config.zip files from
  1. TARGET_BUILD_UNBUNDLED_IMAGE=true m dexpreopt_config_zip
  2. m dexpreopt_config_zip
  (note that m clean should run between steps)
Test: build aosp_cf_x86_64_phone,  launch_cvd, and then
  adb wait-for-device \
      && adb root \
      && adb logcat \
      | grep -E 'ClassLoaderContext [a-z ]+ mismatch' -C 1
      and then check if there is no message.
