[OE-core] [PATCH v5] coreutils: Move stdbuf into an own package coreutils-stdbuf

[Adrian Bunk]

The coreutils implementation of stdbuf uses LD_PRELOAD
to dynamically load libstdbuf which calls setvbuf().
This can't be implemented simply in busybox since it produces
one or two statically linked executables. Therefore, stdbuf
should be packaged separately for people who are using busybox
instead of coreutils for the other tools.

coreutils depends on the new package,
so nothing changes when installing coreutils.
