Ensure the signed arithmetic won't overflow, expand shells tested with (#701)

Browse Source 
* Normalize naming for the stack size CI file

* Extend stack size CI with `posh` and `lksh`

`posh` is a derivative of `pdksh` explicitly intended for ensuring
Debian-policy-compliance.

`lksh` is more-POSIX-esque, legacy shell included along-side `mksh`.

* Ensure a signed long overflow won't occur

Also fixes `write_bytes` when the written bytes have alphabetical digits when
encoded as hexadecimal.

* Improve sh semantics in stack-size workflow
