weston-init: Fix WESTON_USER typo
Commit
837c786d600ba69('weston-init: Add support for non-root start') added a
typo that uses WEST_USER instead of WESTON_USER variable when chwon'ing the
XDG_RUNTIME_DIR directory. Since WEST_USER is not defined, it will `chown
:$WESTON_USER file`, which will work, but that is not 100% correctly and should
be fixed.
This patch basically fix the typo and now the file will be chown'ed to the
WESTON_USER user.
