pkg/epoch: fix tests on macOS

Browse Source 
These tests were failing on my macOS; could be the precision issue (like on
Windows), or just because they're "too fast".

    === RUN   TestSourceDateEpoch/WithoutSourceDateEpoch
        epoch_test.go:51:
                Error Trace:	/Users/thajeztah/go/src/github.com/containerd/containerd/pkg/epoch/epoch_test.go:51
                Error:      	Should be true
                Test:       	TestSourceDateEpoch/WithoutSourceDateEpoch

This patch:

- updates the rightAfter utility to allow the timestamps to be "equal"
- updates the asserts to provide some details about the timestamps
- uses UTC for the value we're comparing to, to match the timestamps
  that are generated.
