If we are running in a user namespace, don't try to mknod as
it won't be allowed. libcontainer will bind-mount the host's
devices over files in the container anyway, so it's not needed.
The chrootarchive package does a chroot (without mounting /proc) before
its work, so we cannot check /proc/self/uid_map when we need to. So
compute it in advance and pass it along with the tar options.

Adds support for the daemon to handle user namespace maps as a
per-daemon setting.
Support for handling uid/gid mapping is added to the builder,
archive/unarchive packages and functions, all graphdrivers (except
Windows), and the test suite is updated to handle user namespace daemon
rootgraph changes.

This change modifies the chmod bits of build context archives built on
windows to preserve the execute bit and remove the r/w bits from
grp/others.
Also adjusted integ-cli tests to verify permissions based on the platform
the tests are running.
Fixes#11047.

Currently TestBuildRenamedDockerfile fails since passing
custom dockerfile paths like:
docker build -f dir/file .
fails on windows because those are unix paths. Instead, on
windows accept windows style paths like:
docker build -f dir\file .
and convert them to unix style paths using the helper we
have in `pkg/archive` so that daemon can correctly locate
the path in the context.

Currently pkg/archive stores nested windows files with
backslashes (e.g. `dir\`, `dir\file.txt`) and this causes
tar not being correctly extracted on Linux daemon.
This change assures we canonicalize all paths to unix
paths and add them to tar with that name independent of platform.
Fixes the following test cases for Windows CI:
- TestBuildAddFileWithWhitespace
- TestBuildCopyFileWithWhitespace
- TestBuildAddDirContentToRoot
- TestBuildAddDirContentToExistingDir
- TestBuildCopyDirContentToRoot
- TestBuildCopyDirContentToExistDir
- TestBuildDockerignore
- TestBuildEnvUsage
- TestBuildEnvUsage2

pkg/archive contains code both invoked from cli (cross platform) and
daemon (linux only) and Unix-specific dependencies break compilation on
Windows. We extracted those stat-related funcs into platform specific
implementations at pkg/system and added unit tests.
