[Buildroot] [git commit] package/containerd: fix btrfs handling

[Peter Korsgaard]

commit: https://git.buildroot.net/buildroot/commit/?id=43ca417c0c883f245dde9be82d49c49adaceea2c
branch: https://git.buildroot.net/buildroot/commit/?id=refs/heads/master

btrfs handling doesn't depend on btrfs-progs but on kernel >= 4.12 since
bump to version 1.7.7 in commit 79e01ef9506a6cdc4836912607dc594ae7b1999d
and
https://github.com/containerd/containerd/commit/024a748c092cbddde0918f2e93a646ce50116e11
resulting in the following build failure:

In file included from vendor/github.com/containerd/btrfs/v2/btrfs.go:21:0:
./btrfs.h:19:2: error: #error "Headers from kernel >= 4.12 are required on compilation time (not on run time)"
 #error "Headers from kernel >= 4.12 are required on compilation time (not on run time)"
  ^~~~~
