Add all upstream syscalls to tables 

Package strace is missing some syscalls we actually implement (e.g.,
getrandom). We also see newer syscalls sometimes (e.g., membarrier) that would
be handy to have formatted.

Let's go ahead and add all syscalls in the latest upstream release (v5.4), even
though we only intend to implement v4.4. None of them are implemented, just
included as placeholders.
