[CRIU] [PATCH] rpc: add log_file field to opts, add defaults toi log.h and use them where needed

[Ruslan Kuprieiev]

Hi!

As we are to add new types of requests to rpc, it would be in handy to 
have ability to set logfile name. So lets add log_file field to rpc 
opts, and set DEFAULT_***_LOG_FILENAME if log_file == NULL.
