futpib 61b7b2d5dc Use rename instead of copy for log file rotation at startup
Replace the expensive file copy in Logs::instanceChecked() with an
atomic rename. The old code copied log_startX.txt to log.txt then
deleted the original, which took ~83ms of synchronous I/O. A simple
rename on the same filesystem is nearly instant (~0.3ms).
