s3:registry: fix invalid write in iconvert_talloc()

For a non-preallocated dest-string and sourcestring of len < 2,
(one or both of the) final two two zero-bytes would be written
after the end of the allocated dest-string. The sourcelen did
not include the source string terminator. For longer strings,
this was not a problem because the dest-string would have been
reallocated in the convert-loop. This is fixed now by allocating
two extra bytes for the terminating 0-bytes that are needed anyways
in the initial allocation.
