I did something similar:

apps:
  git:
    command: usr/bin/git
    plugs: [...]

This way I could mess around with charm.git and play with environment
variables. At the end of the day GIT_EXEC_PATH and PREFIX were needed.

Even still I'm having issues with things like `git clone --recursive` so
I've patched those calls out of the source code for now (when not needed).
I'll keep playing around to see if I can get git-submodules to work but 95%
of the use cases for the tool are functioning now.

I spent quite a long time with strace against charm.git, but that lead to
more problems than help. I've not used `snap try` yet.
