fs: Refactor UtimesNano replacements
...
Previously, nodeRestoreTimestamps would do something like
if node.Type == restic.NodeTypeSymlink {
return nodeRestoreSymlinkTimestamps(...)
}
return syscall.UtimesNano(...)
where nodeRestoreSymlinkTimestamps was either a no-op or a
reimplementation of syscall.UtimesNano that handles symlinks, with some
repeated converting between timestamp types. The Linux implementation
was a bit clumsy, requiring three syscalls to set the timestamps.
In this new setup, there is a function utimesNano that has three
implementations:
* on Linux, it's a modified syscall.UtimesNano that uses
AT_SYMLINK_NOFOLLOW and AT_FDCWD so it can handle any type in a single
call;
* on other Unix platforms, it just calls the syscall function after
skipping symlinks;
* on Windows, it's the modified UtimesNano that was previously called
nodeRestoreSymlinkTimestamps, except with different arguments.

fs: Use AT_FDCWD in Linux nodeRestoreSymlinkTimestamps
...
There's no need to open the containing directory. This is exactly what
syscall.UtimesNano does, except for the AT_SYMLINK_NOFOLLOW flag.

This does not produce exactly the same messages, as it inserts newlines

might be a good thing.

fs: fix race condition in get/set security descriptor

Calling `Load()` twice for an atomic variable can return different

descriptor with high privileges, but then not entering the code path to
switch to low privileges when another thread has already done so
concurrently.
