unix.Errno is of type `uintptr`, which is an unsigned integer. It was being
casted to `int`, which is a signed integer of the same size. This cast could
overflow due to unsigned -> signed.

linuxerr.IsValid just checks if the errno is less than the max possible errno
value. syserr.IsValid additionally checks if the errno can be translated by the
syserr package.
Furthermore, drop the usage of linuxerr.TranslateError(), which only checks
against a map with 3 entries of sentry-internal errors. Earlier, connError()
would always fail at this step and end up returning linuxerr.EINVAL even if the
errno being returned is valid.

- Stub out sighandling functions with panics on Darwin
- Put Linux-specific errors into their own syserr file
Not sure how best to get automated tests running, so I'll leave that for a later
change.

The syscall package has been deprecated in favor of golang.org/x/sys.
Note that syscall is still used in the following places:
- pkg/sentry/socket/hostinet/stack.go: some netlink related functionalities
are not yet available in golang.org/x/sys.
- syscall.Stat_t is still used in some places because os.FileInfo.Sys() still
returns it and not unix.Stat_t.
Updates #214
