Fix hostid mismatch bug that prevented booting installed systems

Root cause: The `hostid` command returns a value even without /etc/hostid,
but `zgenhostid` generates a DIFFERENT random value. The install script
was calling `hostid` for the GRUB kernel parameter, then later calling
`zgenhostid` to create /etc/hostid - resulting in a mismatch.

ZFS refuses to auto-import pools when spl.spl_hostid doesn't match
/etc/hostid, causing "Failed to mount /sysroot" at boot.

Fix: Generate hostid with zgenhostid FIRST (in configure_bootloader),
then read the consistent value for the GRUB kernel parameter. The
configure_zfs_services function now just copies the already-existing
/etc/hostid to the installed system.

Verified in VM: GRUB and /etc/hostid both show identical values after
installation.
