Magnus Kroken 289f2a8ce3 scripts/getver.sh: append short git hash based on upstream commit
The short git hash suffix printed by getver.sh is taken from the
latest local commit, change this to use the hash from latest
upstream commit if available. This is considered the intended
behavior based on commit message a642a11fac,
introducing getver.sh.
