Enable softraid(4) support in installboot(8)

riscv64 efiboot already supports booting from softraid volumes.

These installboot bits make sure that the boot loader will be installed on
chunk devices rather than the volume for root on softraid installations,
i.e. full boot support for riscv64, just like amd64, arm64 and sparc64.

regress is happy.

OK kettenis

Make installboot on landisk aware of a possible MBR on the disk, and in this
case install the first level bootstrap at the beginning of the of the wd0a
filesystem, rather than at the beginning of the disk.

Both locations work but the previous behaviour overwriting an existing MBR
is a violation of POLA.

Add initial piece for softraid(4) support on arm64

arm64 is the only currently supported OpenBSD platform which both
a) supports booting off root on softraid(4) (kernel and bootloader) and
b) is an EFI platform (as far as installboot(8) is concerned).

Currently, installboot treats softraid root volumes as regular devices,
ignoring ignores chunk devices completely.

Teach installboot the first bits of softraid support for EFI:
installing the single-stage boot loader on chunks rather than the volume.

Copy over sparc64's softraid stage-1 code as-is and make its stage-2 a NOOP:

# ./obj/installboot -v sd4
Using / as root
installing bootstrap on /dev/rsd4c
using first-stage /usr/mdec/BOOTAA64.EFI
sd4: softraid volume with 1 disk(s)
sd0a: installing boot blocks on /dev/rsd0c
copying /usr/mdec/BOOTAA64.EFI to /tmp/installboot.KuBD4zkfpM/efi/boot/bootaa64.efi
writing /tmp/installboot.KuBD4zkfpM/efi/boot/startup.nsh

arm64 miniroot fits and boots with this.

OK stsp


As of now, EFI partitions must still be created manually as installboot's
'-p' does not support softraid at all (next missing piece for root on
softraid on arm64 installations to work out-of-the-box).

Rename armv7_installboot.c to efi_installboot.c.

The code is common to EFI platforms, not specific to armv7.
