[0.4.9][SHELL32] Copy without FILE_ATTRIBUTE_READONLY from a CDROM CORE-18089 (#4386)

Browse source 
That problem in the shell was unhidden when we switched from our own to the MS-PL CDFS-driver
in 0.4.8-dev-164-g ec6b3ecbe4
because our own old CDFS driver erroneously never reported any CD file being read-only.

Fix picked from 0.4.15-dev-4348-g 513d0a6d2d

While backporting the fix, I decided to port back also some EOL-whitespace-stripping in that file.
