[libvirt] [PATCH] Don't disable all logging with --disable-debug

This patch changes the automake conditional for debugging to
disable only the debug output, not the entire logging module.
Since the logging symbols are always visible now, I moved them to
libvirt_private.syms and got rid of libvirt_debug.syms. I noticed
that debugFlag wasn't being used anymore, so I removed that too.

There was some code in __virExec where if you called with NULLs
for childout and childerr, it would conditionally set the fds to
either -1 or the /dev/null fd depending on ENABLE_DEBUG. I'm not
sure why the difference, but it seemed safe to remove the entire
conditional section since either setting is effectively treated
the same way in the following code.
