Subject: [PATCH] trace-listen: add missing header

The PATH_MAX macro requires the limits.h header. This fixes build with musl
libc:

.../trace-cmd-trace-cmd-v2.6.1/trace-listen.c: In function ‘make_pid_name’:
.../trace-cmd-trace-cmd-v2.6.1/trace-listen.c:167:16: error: ‘PATH_MAX’ undeclared (first use in this function)
  snprintf(buf, PATH_MAX, VAR_RUN_DIR "/trace-cmd-net.pid");
                ^~~~~~~~
