write_file(): drop "gently" formjk/no-write-file-gently

We have two forms of write_file(): one that dies, and one
that returns an error. However, the latter has only a single
caller, which immediately dies anyway (after producing a
message that is not really any more informative than
write_file's generic die(), and arguably worse because it
does not give the actual filename).

Let's convert that site to use the non-gentle form. At that
point the gentle form has no callers, and we can simplify
the implementation of write_file.
