Fixed OpenSSL deprecation bug on some OSs, causing problems in libgit2
Until this commit, the configure step would fail with an error when compiling libgit2 on a test system. The origin of this bug, on the OS that was tested, appears to be that in OpenSSL Version 1.1.1a, openssl/ec.h fails to include openssl/openconf.h. The bug is described in more detail at https://savannah.nongnu.org/bugs/index.php?58263 With this commit, this is fixed by manually inserting a necessary components. In particular, `sed` is used to insert a preprocessor instruction into `openssl/openconf.h`, defining `DEPRECATED_1_2_0(f)`, for an arbitrary section of code `f`, to include that code rather than exclude it or warn about it. This commit is valid provided that openssl remains at a version earlier than 1.2.0. Starting at version 1.2.0, deprecation warnings should be run normally. We have thus moved the version of OpenSSL in `versions.conf' to the section for programs that need to be manually checked for version updates with a note to remind the user when reaching that version. Other packages that use OpenSSL may benefit from this commit, not just libgit2.
