BUG/MINOR: stats: Fix Lua's get_stats function

Lua's `get_stats` function stopped working in
4cfb0019e6, due to the addition a new field
ST_F_PROTO without a corresponding entry in `stat_fields`.

Fix the issue by adding the entry, like
a46b142e88 did previously for a different field.

This patch fixes GitHub Issue #2174, it should be backported to 2.8.
