[PATCH 2/2] checkout: fix attribute handling in checkout all

[Steffen Prohaska <prohaska@zib.de>]

We need to check out .gitattributes files first to have
them in place when we check out the remaining files. This
is needed to get the right attributes during checkout,
for example having the right crlf conversion on the first
checkout if crlf is controlled by a .gitattribute file.

This works only together with the commit

'attr: fix attribute handling if .gitattributes is involved'

which ensures that .gitattributes files do not trigger the
attribute machinery too early.
