[syserror] Add linuxerr package.
Add linuxerr package to replace syserror and syserr errors. This is done
to improve performance comparing/returning errors to on par with
syscall.Errno.
The below linuxerr_test (formerly syserror_test) shows linuxerr.Error
on par with unix.Error (syscall.Errno) as desired.
