uftrace: Move logfile path to uftrace.data

Ensure that when using "--logfile=<name>", the logfile is created
inside the uftrace.data directory.

Additionally, when using both "--host" and "--logfile" options
simultaneously on the client, the logfile in the uftrace.data
directory is sent to the host.
