security/py-openssl: unbreak run for consumers

Partially revert r566075 to previous py-openssl release only for
${OSVERSION} < 1200085 and base OpenSSL 1.0.2 with PORTEPOCH bump

This step is needed because since 20.0 release py-openssl have dropped off support
for openssl < 1.1.0 which still in base fo FreeBSD 11.4+ branch

Due to dependency on recent cryptography, bump py-cryptography to 3.3.2 release
under same conditions as py-openssl. 3.3.2 was last release which not requred Rust to build
