largefiles: write .hg/largefiles/ files atomically

Before, it was possible to create a

  .hg/largefiles/hash

file with truncated content, i.e., content where

  SHA-1(content) != hash

This breaks the fundamental invariant in largefiles that the file
content for files in .hg/largefiles hash to the filename.
