Recount at 2.2% once the eight bool predicates convert

The port landed on andrew/akbasic as libakstdlib-26, and converting the eight
sites the first count wrote off moves the figure from 301/13 to 313/7 --
2.2% bypassed on the same tree, against 86.4% before the port.

Those eight were the whole of #38, which asked this library for a form a bool
predicate could call. That was ruled invalid: a function which cannot report
an error changes its own signature instead. Seven did, and the eighth is a
bsearch(3) comparator whose signature libc fixes, so it has nowhere to put an
out parameter. Record that the wrapper shape was right and the consumer's
signatures were wrong, because the first count assumed the opposite.

What is genuinely left is six snprintf sites that want truncation as an
answer -- #34 -- and the comparator, which nothing tracks. #38 attributed it
to akbasic #14; that is a mis-citation and #14 is an unrelated issue.

Correct the call profile for the new total, and note two findings the port
produced rather than measured: a file descriptor leak in akbasic's DLOAD,
caught by the ATTEMPT/CLEANUP rule the conversion forced somebody to obey,
and a latent collision in its host-type registration.
