oom_watcher: fix testifylint failures

Fixed the following testifylint failures:

oom_watcher_linux_test.go:68:2: require-error: for error assertions use require (testifylint)
  assert.NoError(t, oomWatcher.Start(tCtx, node))
  ^
oom_watcher_linux_test.go:128:2: require-error: for error assertions use require (testifylint)
  assert.NoError(t, oomWatcher.Start(tCtx, node))
  ^
oom_watcher_linux_test.go:165:2: require-error: for error assertions use require (testifylint)
