[CI] Unbreak the windows cross builds
[CI] Unbreak the windows cross builds

Summary:
The windows cross build is failing due to this bug:
https://sourceware.org/bugzilla/show_bug.cgi?id=26588

This is due to the leveldb tests being built with ASLR enabled but not exporting any symbol, triggering the bug. Until a proper fix is found, unbreak the build by skipping the test install step.

Test Plan:
  ./contrib/teamcity/build-configurations.py build-win64
