Subject: Bug #247370 - Use a private PORTAGE_TMPDIR for --fetchonly mode in
 order do avoid locking the normal build dir location (similar to bug
 #245231). The EbuildFetchPretend class is renamed to EbuildFetchonly and it's
 used for --fetchonly mode regardless of whether --pretend is enabled. Also,
 fix stdout/stderr flushing in JobStatusDisplay.displayMessage() and
 portage.spawn() to ensure output always occurs in the correct order when
 displaying pkg_nofetch() output in --fetchonly mode.
