[PATCH] winevdm: Abstract references to /dosbox

[Gerald Pfeifer]

A user has shared the want to go with dosbox-staging instead of
classic DOSBox. To make that easier, and our current code easier
to maintain, abstract references to /dosbox.

On the way use strlen() instead of sizeof(). That is already used
earlier in that function, it is more robust, and still computed at
compile time if feasible.
