virtiofsd: add --rlimit-nofile=NUM option
Make it possible to specify the RLIMIT_NOFILE on the command-line.
Users running multiple virtiofsd processes should allocate a certain
number to each process so that the system-wide limit can never be
exhausted.
When this option is set to 0 the rlimit is left at its current value.
This is useful when a management tool wants to configure the rlimit
itself.
The default behavior remains unchanged: try to set the limit to
1,000,000 file descriptors if the current rlimit is lower.
