Subject: [PATCH] Fix system colour change for wxVListBox

Remove the background colour setting from wxVListBox::Create() so that
the control uses the up-to-date background colour in the paint event
handler. This way the control responds to system colour changes.

The comment about transparent drawing is wrong since 0975a8a (Applied
patch [ 1405821 ] wxVListBox double-buffering + fix to a scrolling issue
By Jaakko Salli, 2006-01-17).

Closes #26636.
