xbps-src: multiple improvements to messages and phases.

- Prefix all messages with 'Package 'pkgname (version)': ..." to really
  understand what's going on. Add more messages in some stages...
- Do not run pre/post_{configure,build,install} or do_{build,install} stages
  if they were executed successfully in the past.
