ArmPkg/SemiHosting: Recognise '.' directory as the root directory.
Add '.' to the list of directories recognised as the root directory
of semi-hosting.
This is important for EdkShell because listing files in the root directory
of semi-hosting (e.g. ls fsnt0:) is tranformed in a way that uses '.'
Without this patch this results in EdkShell hanging and returning
an "Out of resources" error in the end. With this patch the command
is immediately recognised as unsupported.
