Also, drop the now unused cmdutils_read_file(). There is no reason to
have two functions doing essentially the same thing.

This returns something like "v12_dev0-1332-g333a27c". This is much more
useful than the individual library versions, of which there are too
many, and which are very hard to map back to releases or git commits.

It drops everything that cannot be used for re-encoding and/or
streamcopy.

Since commit 934f2d2f5c16df8aad9f401a9fd842b5d9a78b11,
cmdutils_read_file() prints a confusing message on success:

IO error: Success

This is because the error message is printed on the success path as
well. Add the missing condition so that it is only printed on error.
