compositor: print a clear message when XDG_RUNTIME_DIR is not set
Without this patch, Weston would not start with the message:
creating a keymap file for 44012 bytes failed: No such file or directory
If you do not know, that we use XDG_RUNTIME_DIR for that, the message is
very confusing. Therefore implement a clear error message right at the
start if XDG_RUNTIME_DIR is not set.
