rpm: Address review comments

Address comments from [1]. In summary:

- There's no need to define name and version macros - these are
  generated automatically
- Requirements are emitted by the automatic Python dependency generator
  and don't need to be specified manually
- Lines should be < 80 characters and not wrapped with an escape
- Man pages may not be gzipped so don't assume this
