syscall: remove //sysnb comment generating Setreuid for linux/arm64
CL 210639 moved the //sysnb for Setreuid from syscall_linux_$GOARCH.go
to syscall_linux.go but forgot to remove the comment from
syscall_linux_arm64.go which leads to Setreuid being generated twice for
linux/arm64. Remove that //sysnb comment to avoid this.
