[Buildroot] [git commit] package/lbcamera: don't override _CONF_OPTS, but append

[Yann E. MORIN]

commit: https://git.buildroot.net/buildroot/commit/?id=f835da1c6d7ab59f459e66932ccfbfe5d49560b6
branch: https://git.buildroot.net/buildroot/commit/?id=refs/heads/master

Commit 99cc53f3f4 (package/libcamera: add v4l2 compatibility layer
option) incorrectly added the v4l2 option, which makes it so that
the previous options are overrdien.

Fix that by using an append-assignment.
