Editable build in strict mode (#187) prevents git updates and breaks angr management plugins

[ltfish]

Description

#187 installs angr management (and other angr libraries) in strict mode for editable build, which leads to two problems:

• git pull each repo no longer updates the installed libraries because each installed dependency package is copied to .build directories (e.g., you'll see angr exist under angr-management/.build/angr, and it's the version that's used by the installed angr management).
• angr management can no longer list default installed plugins.

Any of the following solutions will work for me:

• Switch back to the non-strict mode of editable build.
• Make strict mode optional in extremely-simple-setup.sh.
• Fix these problems in strict mode.

I am having a hard time to produce this. Regarding git pull, on my machine it isn't copying anything, it is instead creating a symlink in the build directory back to the source file. git pull should work in this case, and you would just need to re-pip-install if the file structure is changed. Regarding, angr management plugins, I also couldn't reproduce, but I did see that plugin tomls were not being packaged correctly, let me know if angr/angr-management#1211 improves on this issue.
