avoid git status

When trying to build out-of-tree, running `git status` will attempt to
write to the .git/ dir which causes a sandbox violation.

Since this code doesn't seem to actually do anything, drop it.

TEST=precq still passes
TEST=build now passes when building out of tree
TEST=`./scripts/getversion.sh` produces good output with clean & dirty trees
