divVerent e808f168a1 internal/gamepaddb: fix mapping support for e.g. dpleft:-a0. (#2335) 
SDL interprets this as "map -1 to 1, map 0 to -1", so we should do the same.

This fix contains two parts:
* Fix the intended output range.
* Also fix the formula to map a range to a range.
The fix does not change behavior if a "-a" mapping isn't used, as in any other case max-min == 1 or max+min == 0.

Fixes #2334
