ci(cygwin): mark all symlink-race regression tests as expected-skipped

Cygwin lacks RESOLVE_BENEATH-equivalent kernel support and the
per-component O_NOFOLLOW fallback also can't be exercised meaningfully
under the cygwin runner's filesystem semantics, so every test that
asserts the secure_relative_open / do_*_at machinery actually blocks
the attack would skip. Make those skips expected in the workflow's
RSYNC_EXPECT_SKIPPED list:

  - chdir-symlink-race
  - chmod-symlink-race
  - bare-do-open-symlink-race
  - sender-flist-symlink-leak
  - daemon-chroot-acl
