[PATCH 5/5] src: Detect close_range syscall during virGlobalInit()
The whole purpose of virCloseRangeInit() is to be called
somewhere during initialization (ideally before first virExec()
or virCommandRun()), so that the rest of the code already knows
kernel capabilities. While I can put the call somewhere into
remote_daemon.c (when a daemon initializes), we might call
virCommand*() even from client library (i.e. no daemon).
Therefore, put it into virGlobalInit() with the rest of
initialization code.
