perf tools: Fix old GCC build error in trace-event-parse.c:parse_proc_kallsyms()
Old GCC (4.1) does not see through the code flow of parse_proc_kallsyms()
and gets confused about the status of 'fmt':
util/trace-event-parse.c: In function ‘parse_proc_kallsyms’:
util/trace-event-parse.c:189: warning: ‘fmt’ may be used uninitialized in this function
make: *** [util/trace-event-parse.o] Error 1
Help out GCC by initializing 'fmt' to NULL.
