Remove --bin_dir option from tesstrain.sh (should use $PATH instead)
The --bin_dir option to tesstrain.sh is not useful, as $PATH does the same job much better, so switch to relying on that instead. This also makes the code a bit more readable, as it removes the need to refer to binaries as COMMAND_NAME_EXE rather than just command_name.
