Bryan C. Mills f9197a7043 run.{bash,bat,rc}: use ../bin/go instead of the go binary in $PATH
https://golang.org/doc/contribute.html#quick_test currently suggests
running 'make.bash' and 'run.bash' separately, but 'run.bash'
potentially uses a 'go' command resolved from the wrong GOROOT,
which in turn sets the wrong GOROOT for further commands.

Updates #17896
