In these cases, omitempty doesn't really work so it is useless,
but omitzero actually works.
As a result, output of `runc events` may omit these fields if all they
contain are zeroes.
NOTE this might be a breaking change.

I was pretty sure we have a linter for these but apparently we did not.

This removes libcontainer/cgroups packages and starts
using those from github.com/opencontainers/cgroups repo.
Mostly generated by:
git rm -f libcontainer/cgroups
find . -type f -name "*.go" -exec sed -i \
's|github.com/opencontainers/runc/libcontainer/cgroups|github.com/opencontainers/cgroups|g' \
{} +
go get github.com/opencontainers/cgroups@v0.0.1
make vendor
gofumpt -w .

We read output from the following files if they exists:
- cpu.pressure
- memory.pressure
- io.pressure
Each are in format:
```
some avg10=0.00 avg60=0.00 avg300=0.00 total=0
full avg10=0.00 avg60=0.00 avg300=0.00 total=0
```

Amend runc features to print seccomp flags. Two set of flags are added:
* known flags are those that this version of runc is aware of;
* supported flags are those that can be set; normally, this is the same
set as known flags, but due to older version of kernel and/or
libseccomp, some known flags might be unsupported.
This commit also consolidates three different switch statements dealing
with flags into one, in func setFlag. A note is added to this function
telling what else to look for when adding new flags.
Unfortunately, it also adds a list of known flags, that should be
kept in sync with the switch statement.

The libcontainer network statistics are unreachable without manually
creating a libcontainer instance. To retrieve them via the CLI interface
of runc, we now expose them as well.

The event types are now part of a dedicated public `types` package
within runc to be able to unmarshal the output `runc events` directly.
