Description:
The ibuffer directory filter is not buffer aware for buffers not
visiting files. This bug seems to be introduced by commit 3ef18c7a213,
which made the `default-directory` no longer run within
`with-current-buffer`.

Steps:
1. emacs -Q (29.0.50 master d04433b96215d7d3387573f19cc315de86f2341a)
2. M-x dired /home/myuser/foo
3. M-x compile ls -lha
4. M-x ibuffer
5. / F /home/myuser/foo

Expected: filter is applied and two buffers are shown: `foo` and
`*compilation*`.

Actual: only buffer `foo` is shown.

Patch:
Below there is a proposed patch. I did a quick inspection and could not
find similar regressions in other ibuffer filters.
