fp6-vendor-blobs: ship a systemd preset so the unit stays enabled

Browse source 
The package installs a multi-user.target.wants symlink, but that alone does
not survive image build: pmbootstrap runs systemctl preset-all, which removes
manually-installed .wants links for any unit whose preset does not enable it.
The 2026-08-24 image therefore shipped the service as
'disabled; preset: disabled' and it never ran, so aw88261_acf.bin was never
extracted from the stock vendor partition and a fresh install came up with no
sound card at all.

Reproduced and verified on the dev phone: with no preset file installed,
systemctl preset leaves the unit disabled; with it, the unit comes back enabled
and stays enabled across a full preset-all.

Investigation and evidence: fp6 repo journal/blobs/, 2026-08-28.
