Define our own posix_isatty if posix extension is not installed.

Removes the extension dependency on non-windows for parserTests.
Currently used on install-utils.inc readconsole(), eval.php and parserTests.inc

Maintenance scripts receive it via commandLine.inc -> Maintenance.php .. doMaintenance.php -> install-utils.inc
