[PATCH 07/12] mingw: only enable the MSYS2-specific stuff when compiling in MSYS2

["Johannes Schindelin via GitGitGadget" <gitgitgadget@gmail.com>]

From: Johannes Schindelin <johannes.schindelin@gmx.de>

The tell-tale is the presence of the `MSYSTEM` value while compiling, of
course. In that case, we want to ensure that `MSYSTEM` is set when
running `git.exe`, and also enable the magic MSYS2 tty detection.
