git p4 test: use LineEnd unix in windows tests too

In all clients, even those created on windows, use unix line
endings.  This makes it possible to verify file contents without
doing OS-specific comparisons in all the tests.

Tests in t9802-git-p4-filetype.sh are used to make sure that
the other LineEnd options continue to work.
