Since f6ecc62dbf (write_shared_index(): use tempfile module, 2015-08-10)
write_shared_index() has been using mks_tempfile() to create the
temporary file that will become the shared index.
But even before that, it looks like the functions used to create this
file didn't call adjust_shared_perm(), which means that the shared
index file has always been created with 600 permissions regardless
of the shared permission settings.
This means that on repositories created with `git init --shared=all`
and using the split index feature one gets an error like:
fatal: .git/sharedindex.a52f910b489bc462f187ab572ba0086f7b5157de: index file
open failed: Permission denied
when another user performs any operation that reads the shared index.
Let's fix that by using create_tempfile() instead of mks_tempfile()
to create the shared index file.
