DO NOT MERGE: Initialize the ZipArchive to zero before parsing

The fields of the ZipArchive on the stack are not initialized before we
call libminzip to parse the zip file. As a result, some random memory
location is freed unintentionally when we close the ZipArchive upon
parsing failures.

Bug: 35385357
Test: recompile and run the poc with asan.

The Recovery Image

Quick turn-around testing

mm -j && m ramdisk-nodeps && m recoveryimage-nodeps

# To boot into the new recovery image
# without flashing the recovery partition:
adb reboot bootloader
fastboot boot $ANDROID_PRODUCT_OUT/recovery.img

Running the tests

# After setting up environment and lunch.
mmma -j bootable/recovery

# Running the tests on device.
adb root
adb sync data

# 32-bit device
adb shell /data/nativetest/recovery_unit_test/recovery_unit_test
adb shell /data/nativetest/recovery_component_test/recovery_component_test

# Or 64-bit device
adb shell /data/nativetest64/recovery_unit_test/recovery_unit_test
adb shell /data/nativetest64/recovery_component_test/recovery_component_test
