TUCKER: Confine Bud to walkable area when entering club

When Bud is walked to specific coordinates using the 'buw' opcode the
walkable area is not enforced (_locationMaskIgnore == true).
This is usually not a problem because the player is not allowed to click,
however, when entering the club, this allows the player to move Bud to
coordinates from which he can never return, leaving him stuck there.
As a workaround, do not ignore the location mask during this specific
action when entering the club.

Fixes Trac#5838.
