fuse3: update to 3.18.1

[NyaaaWhatsUpDoc]

Testing the changes

• I tested the changes in this PR: briefly for fuse3, flatpak, NO for the others

Local build testing

• I built and ran checks this PR locally for my native architecture, x86-64-glibc

Note that flatpak, gnome-connections, gvfs, sqsh-tools, xdg-desktop-portal succeed in the check build stage, but fails on args passed to meson (which is obviously unrelated to any of the changes here) fixed after #59100

wimlib fails on the following check, but this currently exists on master too:

SKIP: tests/test-imagex-ntfs
FAIL: tests/test-imagex-mount
PASS: tests/test-imagex-update_and_extract
PASS: tests/test-imagex
PASS: tests/test-imagex-capture_and_apply

Can you rebase your PR on current master? meson test issues should be resolved.
