Linux use the task.thread.uw.tp_value field to store the
TLS pointer on arm64 platform, and we use a similar way
in gvisor to store it in the arch/State struct.

pipe and pipe2 aren't ported, pending a slight rework of pipe FDs for VFS2.
mount and umount2 aren't ported out of temporary laziness. access and faccessat
need additional FSImpl methods to implement properly, but are stubbed to
prevent googletest from CHECK-failing. Other syscalls require additional
plumbing.

Example:
epoll_ctl(0x3 anon_inode:[eventpoll], EPOLL_CTL_ADD, 0x6 anon_inode:[eventfd], 0x7efe2fd92a80 {events=EPOLLIN|EPOLLOUT data=0x10203040506070a}) = 0x0 (4.411µs)
epoll_wait(0x3 anon_inode:[eventpoll], 0x7efe2fd92b50 {{events=EPOLLOUT data=0x102030405060708}{events=EPOLLOUT data=0x102030405060708}{events=EPOLLOUT data=0x102030405060708}}, 0x3, 0xffffffff) = 0x3 (29.891µs)

glibc defines struct epoll_event in such a way that epoll_event.data.fd exists.
However, the kernel's definition of struct epoll_event makes epoll_event.data
an opaque uint64, so naming half of it "fd" just introduces confusion. Remove
the Fd field, and make Data a [2]int32 to compensate.
Also add required padding to linux.EpollEvent on ARM64.

This requires fixing a few build issues for non-am64 platforms.

- Add missing build tags to files in the abi package.
- Add the marshal package as a sentry dependency, allowed by deps_test.
- Fix an issue with our top-level go_library BUILD rule, which
incorrectly shadows the variable containing the input set of source
files. This caused the expansion for the go_marshal clause to
silently omit input files.
- Fix formatting when copying build tags to gomarshal-generated files.
- Fix a bug with import statement collision detection in go-marshal.

A couple other things that changed:
- There's a proper extension registration system for matchers. Anyone
adding another matcher can use tcp_matcher.go or udp_matcher.go as a
template.
- All logging and use of syserr.Error in the netfilter package happens at the
highest possible level (public functions). Lower-level functions just
return normal, descriptive golang errors.

Because the abi will depend on the core types for marshalling (usermem,
context, safemem, safecopy), these need to be flattened from the sentry
directory. These packages contain no sentry-specific details.

The iptables binary is looking for libxt_.so when it should be looking
for libxt_udp.so, so it's having an issue reading the data in
xt_match_entry. I think it may be an alignment issue.
Trying to fix this is leading to me fighting with the metadata struct,
so I'm gonna go kill that.
