arm64 linuxulator syscalls.master style review

[emaste]

Summary

This is a syscalls.master for arm64 linuxulator.

Existing Linuxulator (and other) syscalls.master files are a bit of a mess, with inconsistent wrapping at either 80, 81, about 100, or 108 characters. I have a few different style proposals here for discussion before applying to the whole file.

I have a strong preference for something like #1 where each argument goes on it's own line. That would greatly the ease of changes like D14285. It will also simplify review of type improvements such as adding const to path strings.

Reformat arm64 linux syscalls.master per current style

Equivalent to rS339958 for sys/kern/syscalls.master.

One overzealous replacement here fixed in local tree - should be l_int pkey
