[PATCH as/check-ignore] t0007: fix tests on Windows

[Johannes Sixt <j6t@kdbg.org>]

The value of $global_excludes is sometimes part of the output
that is tested for. Since git on Windows only sees DOS style paths,
we have to ensure that the "expected" values are constructed in
the same manner. To account for this, use $(pwd) to set the value
of global_excludes.

Additionally, add a SYMLINKS prerequisite to the tests involving
symbolic links.
