slot will be used. This is to ensure that we always have valid boot, vbmeta,
bootloader images in the inactive slot.
After writing system_other to inactive slot's system partiiton,
PackageManagerService will read `ro.cp_system_other_odex`, and set
`sys.cppreopt` to "requested". Then, according to
system/extras/cppreopts/cppreopts.rc , init will mount system_other at
/postinstall, and execute `cppreopts` to copy optimized APKs from
/postinstall to /data .
Args:
input_file: The input target-files.zip file.
skip_postinstall: Whether to skip copying the postinstall config file.
