[ros-kernel] regfile.c and ldr/*.c OBJ_CASE_INSENSITIVE

[art yerkes]

Both of these areas in reactos open files with a 0 flags.  This is ok on
VFAT it seems because our vfatfs never considers case in file name matches.
In the ext2 driver and possibly some others we will run into, though, 
case matters if not disabled with OBJ_CASE_INSENSITIVE.  I propose to 
patch these calls to InitializeObjectAttributes to be case insensitive.

Any objections?
