Franck Bui-Huu 32ae2ade46 perf probe: Fix short file name probe location reporting
After adding probes, perf-probe(1) reports the probes locations which include
filenames for certain cases.

But for short file names (whose length < 32), perf-probe didn't display the
name correctly. It actually skipped the first character.

Here's an example where 'icmp.c' was screwed:

   $ perf probe -n -a "icmp.c;sk=*"
   Add new events:
     probe:icmp_push_reply (on @cmp.c)
     probe:icmp_reply     (on @cmp.c)
     probe:icmp_reply_1   (on @cmp.c)
     probe:icmp_send      (on @cmp.c)
     probe:icmp_send_1    (on @cmp.c)
     probe:icmp_error     (on @cmp.c)
     probe:icmp_error_1   (on @cmp.c)
     probe:icmp_error_2   (on @cmp.c)
     probe:icmp_error_3   (on @cmp.c)

This patch fixes this bug in synthesize_perf_probe_point().
