perf probe: Fix build error of builtin-probe.c
I got this build error when building tip tree:
| cc1: warnings being treated as errors
| builtin-probe.c:123: error: 'opt_show_lines' defined but not used
This error is caused by:
| #ifndef NO_LIBDWARF
| OPT_CALLBACK('L', "line", NULL,
| "FUNC[:RLN[+NUM|:RLN2]]|SRC:ALN[+NUM|:ALN2]",
| "Show source code lines.", opt_show_lines),
| #endif
My environment defines NO_LIBDWARF, so gcc treated
opt_show_lines() as garbage. So I moved opt_show_lines() into
#ifndef NO_LIBDWARF ... #endif block.
