[PATCH 2/2] submodule: Tolerate auto/safecrlf when adding .gitmodules

[Brad King <brad.king@kitware.com>]

Temporarily disable 'core.safecrlf' to add '.gitmodules' so that
'git add' does not reject the LF newlines we write to the file
even if both 'core.autocrlf' and 'core.safecrlf' are enabled.
This fixes known breakage tested in t7400-submodule-basic.
