test suite: gitattributes: Test working-tree-encoding suppression

Put a UTF-8 BOM in the middle of the test files, and some gitattribute
settings for working-tree-encoding.  `ISO-8859-1' produces file
corruption.  `UTF-16' produces an error since it doesn't specify BE or
LE, and the file lacks a BOM at the start.

Part of the fix to #901900.  This introduces the desired test failure.
