virtiofsd: print log only when priority is high enough
Introduce "-o log_level=" command line option to specify current log
level (priority), valid values are "debug info warn err", e.g.
./virtiofsd -o log_level=debug ...
So only log priority higher than "debug" will be printed to
stderr/syslog. And the default level is info.
The "-o debug"/"-d" options are kept, and imply debug log level.
