[PATCH 1/1] readelf: add support for more RISC-V note types

[Heinrich Schuchardt]

Add definitions and string values for note types

* NT_RISCV_VECTOR               0x901
* NT_RISCV_TAGGED_ADDR_CTRL     0x902
* NT_RISCV_USER_CFI             0x903

The constants are defined in Linux' tools/include/uapi/linux/elf.h.
