[Buildroot] [PATCH 5/6] apply-patches.sh: change archive management

[ludovic.desroches at atmel.com]

From: Ludovic Desroches <ludovic.desroches at atmel.com>

The way archives were managed was incorrect because the uncompressed archives
were sent directly to the patch command. It means that alphabetical patch
order was not respected.
