perf tools: Fix old GCC build error in 'get_srcline'

trace-event-parse.c:parse_proc_kallsyms()

    Old GCC (4.4.2) does not see through the code flow of get_srcline() and
gets confused about the status of 'file' and 'line':

    CC       /tmp/build/perf/util/srcline.o
  cc1: warnings being treated as errors
  util/srcline.c: In function ¿get_srcline¿:
  util/srcline.c:226: error: ¿file¿ may be used uninitialized in this function
  util/srcline.c:227: error: ¿line¿ may be used uninitialized in this function
  make[1]: *** [/tmp/build/perf/util/srcline.o] Error 1
  make: *** [install] Error 2
  make: Leaving directory `/home/acme/git/linux/tools/perf'
  [acme@fedora12 linux]$

Help out GCC by initializing 'file' and 'line'.
