Bugfix for:[23234] Blender File Browser - Back Button does work with first directory entered?

For !WIN32 systems the fix was in ED_fileselect_set_params
(basically adding the first folder in the sfile->folders_prev list)

For WIN32:
I talked with Nathan (Jesterking) and he agreed that the fix in path_util.c was required too. Without that BLI_path_abs was always making WIN32 paths ending with \ to end with \\
(e.g. C:\Blender\ --> C:\Blender\\)
And this was making the folder to fail ISDIR tests.
