Juan RP 01a9868a70 initramfs-tools: performance and misc fixes.
mkinitramfs: run_bootloader shall be called if -B not specified for delete mode.
mkinitramfs: use find -L when copying scripts files, so that it works
	     in a chroot for xbps-src.
init: do not mount devpts, do not create /var/lock, umount /sys
      and /proc in initramfs.
scripts: simplify them and assume that blkid is used everywhere.
scripts: remove specific stuff for lilo compat.
