build: use long hashes when generating feed.buildinfo

Short hashes are not guaranteed to be unambiguous forever and could
collide if the repo grows over time. Git also estimates how many
characters are roughly required to prevent such a collision and slowly
increases the amount of characters beginning from 6, OpenWrt is already
at 8. Lets use the full hash the have a predictable length and keep
hashes unambiguous forever.
