After some upgrade, it seems that some increased level of libc hardening has been applied, leading to a crash inside the `Lockfile::try_lock()` function on startup.

There is an upstream commit addressing this issue (https://github.com/rakshasa/rtorrent/commit/92bec88d0904bfb31c808085c2fd0f22d0ec8db7) but no release has been formed to include it yet.
