tag/Pool: enable option `zero_initialized` 

Commit 44beae519d caused the MPD
executable to grow by more than 1 MB because the `slots` array
suddenly was not zero-initialized anymore, because the doubly-linked
list is circular, while the singly-linked list is zero-terminated.

This option moves the array back to the `bss` section.
