Fix build failure on riscv64 caused by missing syscall

CamberLoid · CamberLoid · commit 658926bd0fa8 · 2022-05-09T14:42:16.000+08:00
On RISC-V 64-bit linux systems, syscall `dup2()` is not available, therefore
syscall.Dup2 will be undefined and gotop will fail to be built from soure.
This patch updates building target of logging/logging_{other,arm64} and
renames them based on syscall used.
