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.

Update/remove most syserror errors to linuxerr equivalents. For list
of removed errors, see //pkg/syserror/syserror.go.

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.

Add Equals method to compare syserror and unix.Errno errors to linuxerr errors.
This will facilitate removal of syserror definitions in a followup, and
finding needed conversions from unix.Errno to linuxerr.

Move Error struct to pkg/errors package for use in multiple places.
Move linuxerr static definitions under pkg/errors/linuxerr.
Add a lookup list for quick lookup of *errors.Error by errno. This is useful
when converting syserror errors and unix.Errno/syscall.Errrno values to
*errors.Error.
Update benchmarks routines to include conversions.
The below benchmarks show *errors.Error usage to be comparable to using
unix.Errno.

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.

Not allowing this was an oversight.
