bpftool: Fix JSON writer resource leak in version command 



When using `bpftool --version -j/-p`, the JSON writer object
created in do_version() was not properly destroyed after use.
This caused a memory leak each time the version command was
executed with JSON output.

Fix: 004b45c0 (tools: bpftool: provide JSON output for all possible commands)
