appveyor: fix openssl version mismatch warning

yuangongji:

  "Many warnings appear when building and running with Visual Studio 2019 in Appveyor:

   WARN C:\projects\libevent\test\regress_ssl.c:210: Version mismatch for openssl: compiled with 1000214f but running with 1000212f

   Simply add the openssl binary to the "PATH" environment variable to fix it.

   I wrote a simple demo to reproduce it: https://github.com/ygj6/verify
   I see there are dozens of openssl libraries in the system of appveyor: https://ci.appveyor.com/project/ygj6/verify/builds/28290688
   If you do not specify which openssl to use, the system cannot find the correct library."
