Fix the double free in verify_package_compatibility().

"""
void* cookie;
std::unique_ptr<void, decltype(&EndIteration)> guard(cookie, EndIteration);
  ...
EndIteration(cookie);
"""

The above pattern is buggy that frees 'cookie' twice.

Bug: 37413730
Test: Build new recovery and adb sideload a previously crashed package
      that contains 'compatibility.zip'.
