VerificationActivity clones calling Intent

When VerificationActivity receives an Intent, clone the calling Intent's
extras Bundle and pass the whole Bundle into
DynamicSystemInstallationService Intent. Don't unpack and repack the
calling Intent's extras field. Since VerificationActivity aren't using the
contents of the extras Bundle, it shouldn't know about the details of extra.

Test: adb shell am start-activity \
  -n com.android.dynsystem/com.android.dynsystem.VerificationActivity \
  -a android.os.image.action.START_INSTALL \
  --el KEY_USERDATA_SIZE 8589934592 \
  -d file:///storage/emulated/0/Download/aosp_arm64-dsu_test.zip
