Fix false 'libfuse3 not found' warning on Debian/Ubuntu

On Debian/Ubuntu, libfuse3-3 (runtime) installs libfuse3.so.3 but not
the unversioned libfuse3.so symlink — that requires libfuse3-dev. Add
.so.3 variants to the FUSE detection check so users with only the
runtime package don't get a spurious warning.
