tar/asm: remove useless test

The iso-8859-1 archive is already tested round trip, and this test did

tar/storage: Sprintf is unnecessary
...
fmt.Sprintf() vs string() for this []byte conversion is too much and
does not provide any further safety.

tar/storage: work with raw (invalid utf8) names
...
When the entry name is not UTF-8, for example ISO-8859-1, then store the
raw bytes.
To accommodate this, we will have getters and setters for the entry's
name now. Since this most heavily affects the json marshalling, we'll
double check the sanity of the name before storing it in the JSONPacker.
