If fixes an error in sameFsTime which was using `==` to compare two times. The correct way is to use go's built-in timea.Equals(timeb).
In changes_windows, it uses sameFsTime to compare mTim of a `system.StatT` to allow TestChangesDirsMutated to operate correctly now.
Note there is slight different between the Linux and Windows implementations of detecting changes. Due to https://github.com/moby/moby/issues/9874,
and the fix at https://github.com/moby/moby/pull/11422, Linux does not consider a change to the directory time as a change. Windows on NTFS
does. See https://github.com/moby/moby/pull/37982 for more information. The result in `TestChangesDirsMutated`, `dir3` is NOT considered a change
in Linux, but IS considered a change on Windows. The test mutates dir3 to have a mtime of +1 second.
With a handful of tests still outstanding, this change ports most of the unit tests under pkg/archive to Windows.
It provides an implementation of `copyDir` in tests for Windows. To make a copy similar to Linux's `cp -a` while preserving timestamps
and links to both valid and invalid targets, xcopy isn't sufficient. So I used robocopy, but had to circumvent certain exit codes that
robocopy exits with which are warnings. Link to article describing this is in the code.
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

All the go-lint work forced any existing "Uid" -> "UID", but seems to
not have the same rules for Gid, so stat package has calls UID() and
Gid().
