Nguyễn Thái Ngọc Duy 82fde87ff3 setup: update the right file in multiple checkouts ...

This code is introduced in 23af91d (prune: strategies for linked
checkouts - 2014-11-30), and it's supposed to implement this rule from
that commit's message:

 - linked checkouts are supposed to keep its location in $R/gitdir up
   to date. The use case is auto fixup after a manual checkout move.

Note the name, "$R/gitdir", not "$R/gitfile". Correct the path to be
updated accordingly.

While at there, make sure I/O errors are not silently dropped.
