INSTALL: document a simpler way to run uninstalled builds
The new scripts automatically saved in the bin-wrappers directory allow you to run a build when you have neither installed git nor tweaked environment variables. Mention this in INSTALL, along with the slight performance issue of doing so. This can be especially handy for manually testing network-invoked git (from ssh, web servers, or similar), but it is also handy with a plain command prompt.

Interactive Tools package still can install "git", but you can build it
