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.
