OpenBSD now has native XDG_RUNTIME_DIR support in libc via setxdgenv(),
which creates directories at /tmp/run/user/{uid}. The previous fallback
path of /var/run/user/{uid} is not writable by regular users on OpenBSD,
causing applications to unnecessarily fall back to temporary directories.
Split the BSD platform detection to handle OpenBSD separately from
FreeBSD and NetBSD, which both use /var/run/user/{uid}. This aligns
with OpenBSD's official implementation in lib/libc/gen/login_cap.c.
Fixes tox-dev#436

OpenBSD applications using platformdirs were unnecessarily falling back to temporary directories because the default runtime path
/var/run/user/{uid}is not writable by regular users on OpenBSD. 🔒 This issue was reported by OpenBSD package maintainers who noticed the mismatch with the platform's native XDG implementation.OpenBSD now has native
XDG_RUNTIME_DIRsupport in libc via thesetxdgenv()function inlib/libc/gen/login_cap.c, which creates directories at/tmp/run/user/{uid}with proper ownership and permissions. The fix splits the BSD platform detection to handle OpenBSD separately from FreeBSD and NetBSD, which both continue using/var/run/user/{uid}. ✨This change aligns platformdirs with OpenBSD's official implementation while preserving existing behavior for FreeBSD and NetBSD. Applications on OpenBSD will now correctly use the runtime directory created by the system during login instead of falling back to temporary directories.

During investigation, the following official platform documentation was reviewed:
setxdgenv()in login_cap.c - uses/tmp/run/user/{uid}pam_xdgmodule - uses/var/run/xdg/{username}(platformdirs fallback of/var/run/user/{uid}is reasonable)Fixes #436
