tests: give the xls fixture its compound-file byte order mark

Browse Source 
craft-cfb refuses a header without the 0xFFFE mark at offset 28
([MS-CFB] 2.2), so craft-xls's sniff called the fixture LegacyBinary.
The old hand-written parser never read that field, which is why the test
only broke with the switch. The fixture is a real workbook otherwise:
sniff now says Xls and read_xls parses it.
