Rename the scripts that update the policy files
script/commit-current-upstream-policy-docs is now
script/write-upstream-policy-files: it writes the policy files and
commits nothing. script/update-policy is now
script/commit-upstream-policy-files, and make update-policy is now
make commit-upstream-policy-files. test/update-policy.sh follows.
Behaviour is unchanged.
