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.

Removes package syserror and moves still relevant code to either linuxerr
or to syserr (to be later removed).
Internal errors are converted from random types to *errors.Error types used
in linuxerr. Internal errors are in linuxerr/internal.go.
