Correct the error-pool entry: the pin is 1.0.0, upstream locks it

Browse Source 
The largest item in the file said the error pool has no synchronisation of any
kind and that libakstdlib is therefore permanently single-threaded pending a
decision upstream. That is true of deps/libakerror as pinned -- 1.0.0, zero
occurrences of akerr_mutex_lock, no lock.h, no thread tests -- and false of
libakerror 2.0.1, which holds one recursive lock over the pool and the status
registry and ships docs/thread-safety.md.

libakgl and akbasic both pin 2.0.1 already.

Issue #2 is retitled and rescoped to the submodule bump and the concurrent test
that has to prove it, rather than a wait on somebody else.
