aes: specify the required OpenSSL version

The code in the aes elements assumes OpenSSL >= 1.1.0:

  - implicit library initialization;
  - version retrieved with OpenSSL_version(OPENSSL_VERSION);

and it fails to build with older versions.

Specify the required OpenSSL version explicitly in meson.build so that
the elements are excluded on older systems (e.g. Ubuntu 16.04) and the
rest of GStreamer can still build.
