Please rebuild FreeBSD 13 box to include patch for virtualbox-ose-additions-nox11

[lwhsu]

https://app.vagrantup.com/bento/boxes/freebsd-13.0

v202104.19.0 contains virtualbox-ose-additions-nox11-6.1.18 but this patch is needed for letting shared folder work:

https://cgit.freebsd.org/ports/commit/?id=8a311de0cb804d8b135413884b4fb336d287ad5a

It is included in 6.1.18_1 and 6.1.20, the pre-built package is available in the official pkg sites so a rebuilt of image should work.

Thanks.
