system_path(): simplify using strip_path_suffix(), and add suffix "git"
At least for the author of this patch, the logic in system_path() was
too hard to understand. Using the function strip_path_suffix() documents
the idea of the code better.
The real change is to add the suffix "git", so that a runtime prefix will
be computed correctly even when the executable was called in /git/ as is
the case in msysGit (Windows insists to search the current directory
before the PATH when looking for an executable).
