Fix gcc8 error about strncpy
With gcc8 we get the following error when stringop-truncation is on: ``` In function ‘_rotate_log_file’, inlined from ‘log_msg.part.2’ at src/log.c:201:17: src/log.c:231:5: error: ‘strncpy’ output truncated before terminating nul copying as many bytes from a string as its length [-Werror=stringop-truncation] strncpy(log_file_new, log_file, len); ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ src/log.c: In function ‘log_msg.part.2’: src/log.c:228:18: note: length computed here size_t len = strlen(log_file); ^~~~~~~~~~~~~~~~ ``` Using memcpy instead of strncpy.
