Because we fetch from urandom under the assumption that the host urandom has
sufficient entropy, we can allow and silently ignore GRND_INSECURE for the
same reason we currently allow and silently ignore GRND_NONBLOCK.
The randomness will be more secure than what was requested, but this is fine.

This will be used to plumb the syscall number through to a counter metric that
exports the number of times an unimplemented syscall has been called.
Plenty of syscall implementations call `EmitUnimplementedEvent` for flags and
settings that are not implemented. With `sysno` available, they will be able
to plumb that bit of information through.

Remove three syserror entries duplicated in linuxerr. Because of the
linuxerr.Equals method, this is a mere change of return values from
syserror to linuxerr definitions.
Done with only these three errnos as CLs removing all grow to a significantly
large size.

New hostarch package contains code not dependent on syserror.

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.
