kernel: Use hardlinks for do_populate_sysroot for speed
The kernel tree is large and doesn't need to be copied. Override the default sysroot handling function to use a hardlink copying function in python. This commit also drops the copying of the /lib directory which just contains the kernel modules. We never use those in the sysroot so there is little point in carrying those around. For linux-yocto this takes the do_populate_sysroot time 24s -> 14s. Signed-off-by: Richard Purdie <richard.purdie@linuxfoundation.org>
