Make /pkgresults/<name> work

[bsiegert]

I had a private email conversation that https://bulktracker.appspot.com/pkgresults/ucon64 shows results for Firefox instead. While this particular bug is fixed, you only get results if you have category and name: https://bulktracker.appspot.com/pkgresults/emulators/ucon64.

Strictly speaking, the category is redundant, so it should work without.

Not quite redundant! My package indexer detects these duplicates:

package name hugo duplicated in categories: games www
package name mdp duplicated in categories: mbone misc
package name xp duplicated in categories: textproc x11
