Plugin update notifications only show in Network Admin, regardless of whether or not they are network activated.

I'm not entirely sure if this is a bug, but it seems like new behaviour to me and it seems a bit strange from an end user perspective.

If you are using WordPress multisite, plugin update notifications only seem to appear in the network area, and not in the plugin list for each subsite.

To reproduce:

1) Set up WP multisite with a site, for example site1
2) Activate Hello Dolly on site1
3) Manually change the version in hello.php to something else
4) Update notification only shows for me in the Network plugin page, and not Site1's plugin page.

I'm happy to try and submit a patch for this if people agree it's a bug.

Plugin update notifications are only shown in network admin since 3.1, see [16037].

In Multisite, plugins can only be updated in network admin anyway, so this appears to be a conscious decision.
