[OSSTEST PATCH 01/10] Flight restriction: Move $maxflight to Osstest::Executive

[Ian Jackson <ian.jackson@eu.citrix.com>]

We are going to move the interpretation of --max-flight into
Osstest::Executive.  Start this by making $maxflight shared between
Executive and the main program.  Later, we will make it no longer
exported.

There are a number of places in Executive where a `my' variable
$maxflight shadows the newly moved global.  These will be got rid of
later, too.

No functional change.
