- Build scripts must be executed by the os/400 shell (sh), not bash which
is a PASE program: The `-ot` non-POSIX test extension works in os/400 as
well. Ref: https://github.com/libssh2/libssh2/pull/1364#issue-2241646754
- Drop/fixup mods trying to make some syntax highlighters happier.

- use `$()` instead of backticks, and re-arrange double-quotes inside.
- add missing `|| exit 1` to `cd` calls. (could be dropped by using `set -eu`.)
- add `-n` to a few `if`s.
- shorten redirections by using `{} >` (as shellcheck recommended).
- silence warnings where variables were detected as unused (SC2034).
- a couple misc updates to silence warnings.
- switch to bash shebang for `-ot` feature.
- split two lines to unbreak syntax highlighting in my editor. (`$(expr \`, `$(dirname \`)
Also enable CI checks for OS/400 shell scripts.
