t0028: fix test for UTF-16-LE-BOM
According to its name, the test is designed for UTF-16-LE-BOM.
However, possibly due to copy&paste oversight, it was using UTF-32.
While the test succeeds (extra \000\000 are interpreted as NUL),
I myself had an unrelated problem which caused the test to fail.
When analyzing the failure I was quite puzzled by the fact that the
test is obviously buggy. And it seems that I'm not alone:

Fix the test to follow its original intention.
