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/. Signed-off-by: Christopher Jones <tophj@linux.vnet.ibm.com> [s390x] switch utsname from unsigned to signed per https://github.com/golang/sys/commit/33267e036fd93fcd26ea95b7bdaf2d8306cb743c char in s390x in the /x/sys/unix package is now signed, so change the buildtags Signed-off-by: Christopher Jones <tophj@linux.vnet.ibm.com> Upstream-commit: 069fdc8a083cb1663e4f86fe3fd9b9a1aebc3e54 Component: engine
