KERNEL: use FILE_SHARE_DELETE when loading modules

Macromedia's Dreamweaver MX uninstaller does this:
CreateFile("uninstall.exe", 0, FILE_SHARE_READ, NULL,
OPEN_EXISTING, FILE_FLAG_DELETE_ON_CLOSE, NULL);
CreateProcess( NULL, "uninstall.exe", NULL, NULL,
TRUE, 0, NULL, NULL, &si, &pi );
The code that deals with loading PE modules presently does not add
FILE_SHARE_DELETE, so CreateProcess fails with a sharing violation.

ChangeLog:
* use FILE_SHARE_DELETE when loading modules, as
running an exe that's going to be deleted should work
