kernfs: Revise command creating the link target in case /dev/shm is a symlink
When /dev/shm is a symlink we need to create its target or some tests
will fail and Python 3 will be misconfigured. We wrote it as:
mkdir -pv $LFS/$(readlink $LFS/dev/shm)
But if $LFS/dev/shm is a relative symlink (say ../run/shm), we end up:
mkdir -pv /mnt/lfs/../run/shm
This command will create /mnt/run/shm, not $LFS/mnt/shm as we expected.
Twist it a little to make it work for both absolute symlinks and
relative symlinks.
