rust: fix fetch-cargo-deps for git dependencies

Browse source 
We need to make sure that `$revs` ends with a space, since files must always
end with newlines. The previous code ignored the last entry in `$revs`, because
read already returns non-zero exit code for the last entry, as it does not end
with a space.
