[Libosinfo] [libosinfo] media: Remove ISO header strings' padding

[Fabiano Fidêncio]

The strings in the ISO header ("volume-id", "system-id", "publisher-id"
and "application-id") have a predefined size and are padded with spaces,
but nothing in on_{pvd,svd}_read() removes these padding spaces from
those strings, which makes osinfo_media_get_volume_id() always return
[SOME-ISO-LABEL                  ] rather than the expected
[SOME-ISO-LABEL].
