Default XDG_SESSION_TYPE to unspecified

Browse Source 
Minimal systems in cases may not have XDG_SESSION_TYPE set at all, causing the program to segfault at the `strcmp`. This commit sets XDG_SESSION_TYPE to `unspecified` (according to https://www.freedesktop.org/software/systemd/man/pam_systemd.html) if it is not defined in the environment.
