Fix memory leak in etc1bitmap GM.

Fix memory leak in etc1bitmap GM.

We never drop our first ref on fileData. (All our ref counts start at one).
SkAutoTUnref<T> is almost always the right thing to use for refcounted types.

No LGTM from a valid reviewer yet. Only full committers are accepted.
Even if an LGTM may have been provided, it was from a non-committer or
a provisional committer, _not_ a full super star committer.
See http://www.chromium.org/getting-involved/become-a-committer
Note that this has nothing to do with OWNERS files.
