CHOP-900: Use new apr_procattr_constrain_handle_set() extension.
Now LLProcess explicitly requests APR to limit the handles passed to any child process, instead of wantonly passing whatever happens to be lying around the parent process at the time. This requires the latest APR build. Also revert LLUpdateDownloader::Implementation::mDownloadStream to llofstream (as in rev 1878a57aebd7) instead of apr_file_t*. Using APR for that file was a Band-Aid -- a single whacked mole -- for the problem more systemically addressed by apr_procattr_constrain_handle_set().
