teamcity: misc changes to CI (#3476)

- add architecture rule for ppc64le so that incompatible agents don't
  pick up the build
- disable PIE tests on linux/ppc64le (the tests claim it doesn't work)
- enable PIE tests on darwin/amd64 now that the entry point calculation
  has been fixed
- remove dependency on wget and curl in the test script for linux to
  reduce test time
- only install git in the linux test script when we need it
- remove staticcheck from linux/ppc64le builds (it takes almost 5
  minutes between installation and execution and makes the test timeout
  sometimes)
- drop windows/arm64/tip build, the windows/arm64 build is broken
  anyway and since there is only one agent it makes CI runs slow
- drop linux/ppc64le/tip build, there is only one agent, it's slow and
  it will always timeout. CI runs in excess of 1h are too long.
