[OE-core][hardknott][PATCH] populate_sdk_base: remove unneeded dirs such as /dev

[Chen Qi]

We met a problem that core-image-tiny-initramfs's SDK cannot be
installed. The error message is like below.

  tar: ./sysroots/core2-64-poky-linux/dev/console: Cannot mknod: Operation not 
permitted

In fact, the '/dev' direcotry is not needed by SDK. So remove it.

This patches uses a variable, SDK_PRUNE_SYSROOT_DIRS, to hold useless dir 
entries
so that it could be extended. For example, '/usr/bin' could be added if wanted.

(From OE-Core rev: 9154f71c7267e9731156c1dfd57397103e9e6a2b)
