eet: Fix 'No OPENSSL_Applink' error message. 

In some systems (such as Windows), OpenSSL raises an error about "No Applink"
(see ["I've compiled a program under Windows and it crashes: why?" in OpenSSL
FAQ](https://www.openssl.org/docs/faq.html#PROG3)). Including only
openssl/applink.c didn't work, so the solution was to replace `FILE*`
interfaces with OpenSSL's BIO API which also contains file operations.
