Fix calculation of how much shared memory is required to store a TOC.

Commit ac883ac453 refactored shm_toc_estimate() but changed its calculation
of shared memory size for TOC incorrectly. Previously this could cause too
large memory to be allocated.

Back-patch to v11 where the bug was introduced.
