chg: verify XDG_RUNTIME_DIR
According to the specification [1], $XDG_RUNTIME_DIR should be ignored
unless:
The directory MUST be owned by the user, and he MUST be the only one
having read and write access to it. Its Unix access mode MUST be 0700.
This patch adds a check and ignores it if it does not meet part of the
criteria.
