[poky] [PATCH 3/8] yocto-bsp: have replace_file() close file before copying

[tom.zanussi at linux.intel.com]

From: Tom Zanussi <tom.zanussi at linux.intel.com>

replace_file needs to make sure the file it's replacing is closed
before replacing it, otherwise unexpected results may ensue.

Fixes [YOCTO #4145].
