automation/console.exp: do not assume expect is always at /usr/bin/

Instead use env to find the location of expect.

Additionally do not use the -f flag, as it's only meaningful when passing
arguments on the command line, which we never do for console.exp.  From the
expect 5.45.4 man page:

> The -f flag prefaces a file from which to read commands from.  The flag
> itself is optional as it is only useful when using the #! notation (see
> above), so  that other arguments may be supplied on the command line.
