libobs: Add desktop session type to Linux log

Browse Source 
Add the content of the XDG_SESSION_TYPE environment variable to
the output log if it is set. This is usually set on modern Linux
distributions and typically carry either "x11" or "wayland" when
run from a desktop environment.

This is independent from the QT_QPA_PLATFORM environment variable
which would allow OBS Studio to run inside a wayland session. The
session type it runs on does have an implication on the behavior of
some plugins like screen and window capture. So having this
information exposed here is extremely helpful for diagnosing
issues.
