Kacper Michajłow 92deed9732 avutil/file: fix av_file_map file mapping on Windows ...

This makes the behavior of av_file_map() the same on Windows as it is on
other platforms. The file is opened as read-only, but the mapping is
copy-on-write, allowing the user to write to the memory pages returned
by av_file_map().

This commit fixes libavutil\tests\file.c test, which would crash when
trying to write to a read-only memory page.
