Fix presigned apk check for privileged apps

The validation checks that run for presigned apps currently expect that
privileged apps have uncompressed dex files but if
DONT_UNCOMPRESS_PRIV_APPS_DEXS is true (UncompressPrivAppDex false) this
doesn't have to be the case so make the validation consistent with this.
Also make TestAndroidAppImport_Preprocessed verify that extra arguments
to 'check_prebuilt_presigned_apk.py' are correct for both privileged and
non-privileged apps.

Test: m nothing --no-skip-soong-tests
Test: Add presigned, privileged android_app_import module with
compressed dex to PRODUCT_PACKAGES for aosp_cf_x86_64_phone,
lunch aosp_cf_x86_64_phone-trunk_staging-userdebug &&
m DONT_UNCOMPRESS_PRIV_APPS_DEXS=true no longer fails due to validation
error.
