syscall.c: define personality names for all multi-personality architectures

I see no reason for not having these definitions for SPARC64 and RISC-V.
Also, borrow the check template from supported_personalities.h.

* syscall.c (update_personality) [defined RISCV, defined SPARC64]
<PERSONALITY_NAMES>: Define it for these architectures.
