bindings: fix init pid hashing

We were stupidly always hashing entry->ino where entry was just freshly
allocated zeroed-memory so we effectively added stuff to the cache
forever but this meant:
- we never found a match when we hashed the actual inode
- we kept growing the cache
- we leaked memory

Closes: #407.
