test: Clean up xfail-{fast,win32} tests

Rename {struct-update,fsu}-moves-and-copies, since win32
failed to run the test since UAC prevents any executable whose
name contaning "update". (#10452)

Some tests related to #9205 are expected to fail on gcc 4.8,
so they are marked as `xfail-win32` instead of `xfail-fast`.

Some tests using `extra::tempfile` fail on win32 due to #10462.
Mark them as `xfail-win32`.
test: Fix signal-exit-status on windows
rustpkg: Disable test suite on windows

sha1, version, util tests are still alive and they pass on win32.
test: Add xfail-win32 to two debug-info tests
doc: Fix example on Windows
auto merge of #10472 : klutzy/rust/cleanup-xfail, r=alexcrichton

Closes #10452.
