envsetup: fixup dopush

* After clobber, $OUT does not exist and tee cannot create .log; fix
  this by calling mkdir -p $OUT
* Make sure Copy and Install are at the beginning of the log line being
  analyzed and also search for ':' so that "Copying:" lines don't count
* Fix Copy file list by quoting so shell doesn't think this is a
  command: $LOC $(...)
* Fix 'only copy files from $OUT' now that multiple file pushing works
  right
* Only stop java services once (if needed) and then wait to restart
  services until after all files have been pushed
* Change location of SystemUI.apk to priv-app
