scripts: match AGP zip alignment in android reproduce build (#7196)

Browse Source 
Release APKs are packaged by AGP (:android:assembleRelease), which
zero-pads ZIP alignment. verify_apk re-aligned the rebuilt APK with
repro-apk's --pad-like-apksigner (the 0xd935 extra-field scheme of
standalone apksigner >= 35.0.0-rc1), so apksigcopier aborted with
"APK Signing Block offset < central directory offset".

Drop the flag so the padding matches AGP's output; the rebuilt APK
then reproduces the published one byte-for-byte.
