riscv64: ensure reasonable partition alignment

[Heinrich Schuchardt]

Currently the RISC-V preinstalled server images come with partitions that are only 1 KiB aligned. Ext4 may use 4 KiB block size. The existing misalignment leads to decreased performance.

Please, decrease the size of the loader2 partition by 34 512-byte blocks. This results in 1 MiB alignment of the EFI and root partitions.

The remaining loader2 partition size of close to 4 MiB is still large enough for U-Boot or a future EDK II.
