Fix patches for glog

There were two problems here:

* The URL for the second patch had a time-sensitive token in it, so I mirrored on gist.github.com
* The second patch depended on the first one, but because it was applied as `p0` it came up first when iterating over the hash. I edited the patch on gist.github.com to add a leading slash to the paths so it could be applied as `p1` and converted the hash to an array.
