pg_upgrade: fix -j race condition on Windows
Pg_Upgrade cannot write the command string to the log file and then call
system() to write to the same file without causing occasional file-share
errors on Windows. So instead, write the command string to the log file
after system(), in those cases.
Backpatch to 9.3.
