Builtin DIR excluding some items (Windows)

Describe the bug

When mounting a Windows local drive in DosBox-X, a DIR should display the same items you'd find with the Windows CMD prompt. In fact, this does not happen.

Consider the following:

MOUNT C C:\
DIR /A C:\
DIR /A C:\Windows\Sys*

You'll find that the first DIR invocation omits directories like "Config.msi", "Recovery", "System Volume Information"; the second, directories like "System32", "SystemApps", "SyetemResources", "SystemTemp", "SysWOW64".

Having reviewed the sources, this seems related to the ht_temp call (wstat64) returning -1 instead of 0 with such directories.

In fact, those are directories with special NTFS access rights.

An Administrator user surely can call wstat successfully on them, but normal users can typically list them without invoking special privileges (i.e. with Explorer, or CMD itself).
