If `unix.Lgetxattr` returns an error, then `sz == -1` which will cause a
runtime panic if `errno == unix.ERANGE`.

Use the symlink xattr syscall wrappers Lgetxattr and Lsetxattr from
x/sys/unix (introduced in golang/sys@b90f89a) instead of providing own
wrappers. Leave the functionality of system.Lgetxattr intact with
respect to the retry with a larger buffer, but switch it to use
unix.Lgetxattr. Also leave system.Lsetxattr intact (even though it's
just a wrapper around the corresponding function from unix) in order to
keep moby building for !linux.

Changes most references of syscall to golang.org/x/sys/
Ones aren't changes include, Errno, Signal and SysProcAttr
as they haven't been implemented in /x/sys/.

[s390x] switch utsname from unsigned to signed
per 33267e036f
char in s390x in the /x/sys/unix package is now signed, so
change the buildtags

This is a package for generic system calls etc that for some reason
is not yet supported by "syscall", or where it is different enough
for the different ports to need portability wrappers.
