update: fix edge-case with update.atomic-file and read-only files

We used to create the tempfile with the original file mode. That means
creating a read-only tempfile when the original file is read-only, which crash
if we need to write on the tempfile.

The file in the working directory ends up being writable with and without the
atomic update config, so the behavior is the same.

Verify enabling a single profile works

  $ hg debugsparse --enable-profile webpage.sparse

Verify enabling two profiles works

  $ hg debugsparse --enable-profile backend.sparse

Verify disabling a profile works

  $ hg debugsparse --disable-profile webpage.sparse

Test checking out a commit that does not contain the sparse profile. The
warning message can be suppressed by setting missingwarning = false in
[sparse] section of your config:

  $ hg debugsparse --reset
  $ hg rm *.sparse
  $ hg commit -m "delete profiles"
  $ hg up -q ".^"
  $ hg debugsparse --enable-profile backend.sparse
  $ ls
  index.html
  readme.txt
  $ hg up tip | grep warning
  warning: sparse profile 'backend.sparse' not found in rev bfcb76de99cc - ignoring it
