Update top_dir with git repo root just when cwd locate in a git repo.

if when execute command "git rev-parse --show-toplevel" in a directory
that is not a subdirectory of a git repo, CheckCallAndFilter will not
throw exception, so the top_dir may be updated with a invalid path.

is this resolved ? i still got the same errors, cant event build from downloaded tarballs, if this features was available, it will lower the stress on git server to always pull permanently.

@kyles You are probably running the gn wrapper script (gn.py in depot_tools), and the wrapper cannot find the actual gn executable which is usually downloaded by `gclient runhooks` IIRC.

For the record, on embedded build systems they often build GN themselves and use that GN binary to build chromium from a tarball. See, for example, https://github.com/rakuco/meta-crosswalk/tree/chromium61/recipes-browser/chromium
