Subject: [syserror] Change syserror to linuxerr for E2BIG, EADDRINUSE, and
 EINVAL

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.
