For --features:
* Most don't create $IPC_SAVE, so don't try to source it in a trap if it
  doesn't exist
* $grep_deps may exist for some features, like --check-depends, so always
  delete it in safe_exit if it exists

Other:
* Don't try to clean out WRKDIRPREFIX if we're not actually building
* In update_contents() streamline the code that handles replacing the file
  if necessary
* Simplify the whitespace in the code that updates dependencies after an
  install, there will always be at least one pm_v printed, so no need to
  be coy about it
