Fix win32 test failure for crypto/openssl_version

From legacy/trac#25549 (moved), the crypto/openssl_version test fails on win32 builds with:

crypto/openssl_version: [forking] openssl version = 1.0.2l
openssl h_version = 1.0.2n
  FAIL ../src/test/test_crypto.c:156: assert(!strcmpstart(version, h_version))
  [openssl_version FAILED]

This could possibly be an artifact of how the CI environment is set up. If so, there should be a CI_WINDOWS environment variable set on the machine, so we can probably just ignore this test?
