selftest: imagefeatures.py: respect IMAGE_LINK_NAME for debugfs and manifest as well

* these cases were correctly respecting IMAGE_LINK_NAME in most tests

* the only exception was relatively wide glob for manifest:
  "test-empty-image-*.manifest"
* and even wider glob for -dbg:
  "*-dbg.rootfs.tar.bz2"

* replace them with the exact filename we expect for given image

* be aware that gzip won't accept the symlink in IMAGE_LINK_NAME causing:

  AssertionError: Command 'gzip -t /OE/build/poky/build/build-st-2023-03-12-todo-patch2/imagefeatures.ImageFeatures.test_bmap/build-st/tmp/deploy/images/qemux86-64/core-image-minimal-qemux86-64.rootfs.ext4.bmap.gz' returned non-zero exit status 1:
  gzip: skipping: /OE/build/poky/build/build-st-2023-03-12-todo-patch2/imagefeatures.ImageFeatures.test_bmap/build-st/tmp/deploy/images/qemux86-64/core-image-minimal-qemux86-64.rootfs.ext4.bmap.gz is a symbolic link

* and "*-dbg.rootfs.tar.bz2" doesn't work if IMAGE_NAME_SUFFIX
  is changed to anything else than ".rootfs" or moved into
  IMAGE_LINK_NAME (like I plan in future changes where this will
  need to be updated again).

  Luckily we can use the symlink which currently doesn't have
  IMAGE_NAME_SUFFIX nor the DATETIME, so we don't need to search
  for it with glob, e.g. currently:

  core-image-minimal-qemux86-64-dbg-20230313112546-dbg.rootfs.tar.bz2
  core-image-minimal-qemux86-64-dbg.tar.bz2 -> core-image-minimal-qemux86-64-dbg-20230313112546-dbg.rootfs.tar.bz2
