To make it easier to use EDK2 on systems other than Linux, where the default shell might
not be bash, I'd like to convert the shell scripts to use POSIX sh where possible.

edksetup.sh and BuildEnv remain bash scripts, but I hope to convert them to sh in a future
changeset.

I did see the argument against using $0 in http://mywiki.wooledge.org/BashFAQ/028, but I'm
not sure anyone using EDK2 will run into problems the article describes.

I checked the scripts with shellcheck.
