want LBA48 support in grub
- we cannot install stage2 beyond 2TB, meaning that we can't boot off EFI partitions beginning beyond 2TB
- when rpool extends beyond 2TB on a disk we can get unexpected boot failures if the grub config file, the kernel, or the bootarchive are stored beyond the 2TB limit

This just fixes the loading of files beyond 2TB.
Fixing loading of stage2 from beyond 2TB turned out to be quite difficult due to requirements for backwards compatibility and the necessity of fixing and testing all the grub commands that read/write it like install, blocklist, embed etc. As this is a rather esoteric feature I shelved that for now.
