[Buildroot] [PATCH v6] bcache-tools: Adding package.

[Jean-Christophe DUBOIS <jcd@tribudubois.net>]

I did not add the Makefile patch for the man8 directory as I agree with 
Thomas that the bcache-tools package should be modified upstream to 
allow install without this dir.

Meanwhile, we can add the man8 dir which is removed by BR afterward.
