commit: https://git.buildroot.net/buildroot/commit/?id=5a9168edd446b9396080cf70d4b64f3717288837
branch: https://git.buildroot.net/buildroot/commit/?id=refs/heads/next

Disable vhost-user on uclibc-ng as it raises build failures since bump
to version 6.0.0 in commit 6b86c9335fc3ff381878156c6243454d4b688df9 and
https://github.com/qemu/qemu/commit/810033be083040591fee2fc09f2f294670ed1930

The issue is that F_ADD_SEALS and F_SEAL_xxx variables are not defined on
uclibc-ng (even if MFD_ALLOW_SEALING is defined) resulting in the
following build failure:

../subprojects/libvhost-user/libvhost-user.c:1637:22: error: 'F_ADD_SEALS' undeclared (first use in this function)
 1637 |     ret = fcntl(*fd, F_ADD_SEALS, flags);
      |                      ^~~~~~~~~~~
