[OE-core] [PATCH] devtool: open kconfig fragment in binary mode

[Stephano Cetola]

When devtool writes to the kconfig fragment, it writes the output of
the diff command returned from pipe.communicate(). This function
returns binary objects. We should open the kconfig fragment file in
binary mode if we expect to write binary objects to it.
