Bug #16861371 SSL_OP_NO_COMPRESSION NOT DEFINED

Description:
Can't build mysql-5.5 latest source with openssl 0.9.8e.

Analysis:
Older OpenSSL versions(prior to openssl 1.0) doesn't have 'SSL_OP_NO_COMPRESSION' defined.
Hence the build is failing with SSL_OP_NO_COMPRESSION undeclared.

Fix:
Added a conditonal compilation for 'SSL_OP_NO_COMPRESSION'.
i.e if 'SSL_OP_NO_COMPRESSION' is defined then have the SSL_set_options call for OpenSSL 1.0 versions.
Have sk_SSL_COMP_zero() call for OpenSSL 0.9.8 version
