server: Bug 581174: Fix path handling for traces when running on Windows

When the trace server is started on Windows where the CWD
is a lower case drive letter the device handling code in
Eclipse does not work. The root cause of this is we
were making a Posix o.e.c.runtime.Path on Windows so the
c: was being identified as a path segment rather than
a device.
