Rollup merge of #107790 - tharunsuresh-code:snap_curl, r=jyn514

 x.py fails all downloads that use a tempdir with snap curl #107722

Have used the open() library from python to capture the binary output of the curl command and write it to a file using stdout of the subprocess. Added a single-line comment mentioning the redirect operator.
