Revert "Fix check for openssl on Windows"

This reverts commit 045e5c5a4460020e513516a5d1f3087094e67da3
For Windows platform, openssl 1.0.2 and earlier versions have
eay64 and eay32 libraries[1]. But from openssl 1.1.0 and above
versions have same library name[2] (libcrypto and libssl) like
other unix-like platforms.
