lxc: uprev to v3.0.0

Update to the latest lxc release. This requires some minor patch
updates (fuzz and offset, not content) along with dropping a no longer
needed fix for gcc7 (gcc 7.3 is everywhere and is patched).

The ptests were already busted before the uprev so I was not able to
run them but I will follow up with a fix for this. I did run against
our usual usecases 'lxc-create', 'lxc-console', 'lxc-ls',
'lxc-destroy', 'lxc-start', 'lxc-execute', 'lxc-attach'... and there
were no issues (outcomes matched v2.0.8).

-Subject: [PATCH] cgroups: work around issue in gcc 7
-
-This works around
-https://bugzilla.yoctoproject.org/show_bug.cgi?id=11672
-https://gcc.gnu.org/bugzilla/show_bug.cgi?id=78969
-
-By removing a single cgroup entry. For the majority of usecases this
-loss of a single entry should not be an issue and once gcc 7 is fixed
-we can revert this.
