[PATCH 2/2] gitk: Add auto-select length preference for SHA256

[Takashi Iwai <tiwai@xxxxxxx>]

This implements the missing preference setup of the auto select length
for SHA256. The variable set via the preference menu is switched
depending on the hash algorithm.

The default auto-select length is set to 64 for SHA256, and
saved/restored as "autosellensha256" in the config.
