perf script: Fix memory 'threads' and 'cpus' leaks on exit
ASan reports several memory leaks while running:
# perf test "82: Use vfs_getname probe to get syscall args filenames"
Two of these are caused by some refcounts not being decreased on
perf-script exit, namely script.threads and script.cpus.
This patch adds the missing __put calls in a new perf_script__exit
function, which is called at the end of cmd_script.
This patch concludes the fixes of all remaining memory leaks in perf
test "82: Use vfs_getname probe to get syscall args filenames".
