perf probe: Fix compiles due to declarations using perf_probe_point

perf fails to build with gcc "(GCC) 4.4.7 20120313 (Red Hat
4.4.7-4.0.9)" (a.k.a., RHEL6 / CentOS 6 / OL 6):

  cc1: warnings being treated as errors
  util/probe-event.c: In function ‘get_alternative_line_range’:
  util/probe-event.c:359: error: missing initializer
  util/probe-event.c:359: error: (near initialization for ‘pp.file’)
  util/probe-event.c:359: error: missing initializer
  util/probe-event.c:359: error: (near initialization for ‘result.function’)

Fix by bringing in initializers to declaration.
