Migrate top(1) to usr.bin

[eadler]

Summary

We've been maintaining top(1) for a long time, and the upstream
hasn't existed/been used in similarly as long. Make it clear that we own
top(1)

Test Plan

I tested make/install world and am in the process of testing universe. I
have little experience with our build system, so I likely messed up
somewhere.

fix keywords

[imp]

looks like you've removed a lot of keywords...

I think that's an artifact of how phab is displaying the diff:

∴svn proplist usr.bin/top/commands.h   
Properties on 'usr.bin/top/commands.h':
  svn:eol-style
  svn:keywords
  svn:mime-type

Do you need to update ObsoleteFiles in order to remove the old version?

This is just moving the source files. It installs to the same place.
