ghidraRun (and launch.sh) both seg fault in some macOS bash
installations via the bash expansions performed in in ghidraRun,
launch.sh, and a few other scripts. This happens on my macports
bash installation and has been reported in homebrew bash
installations as well
(https://github.com/orgs/Homebrew/discussions/6270)
My specific bash that seg faults:
GNU bash, version 5.3.9(1)-release (aarch64-apple-darwin24.6.0)
We can avoid the expansion and use an alternate expansion method.
Scripts were updated via:
```sh
perl -pi -e 's~^(\w+)\s*=\s*"\$\{(\w+)%/\*\}"\s*$~$1="\$(cd "\$(dirname "\$$2")" && pwd)"~' `find Ghidra/RuntimeScripts/Linux/`
```
