trace-cmd: Fix segmentation fault in trace-snapshot
To reproduce the problem:
plugin 'wakeup'
trace-cmd: Device or resource busy
Segmentation fault (core dumped)
When the user triggers a condition such as EBUSY the program should die
gracefully. The problem here is simply caused by an extra conversion
specifier in "die" in the write_file function
