internal/gamepad: fix a typo that caused oddly cut off gamepad names. (#2300)

Browse Source 
This change allows gamepad names up to 256 characters, which is usually
enough. Before, names were cut off after 7 characters, matching the string
"Unknown" that is used if querying the name fails.

Closes #2300
