Update Dreamcast port

[pcercuei]

• The CMAKE_SYSTEM_NAME is defined as lowercase 'dreamcast' by KallistiOS' CMake scripts.
• Added some glue code to allow mapping a SMB server into KallistiOS' virtual filesystem. Users now just need to call kos_smb_init() with a server URL as the argument, to have it mounted as /smb in the VFS.

Merged.
I checked it in but wonder if vfs.c/h shouldn't rather be in the sdk for kallistoos instead of libsmb2.

Up to you, if you prefer we can have it in KallistiOS directly.

It is in a separate dedicated subdirectory so I have no issue with it being in libsmb2.

I was thinking more about discoverability for the KallistoOS developers.
It is easier to discover that this feature exists and is available to devs if it is in the sdk than in a separate third party library.

But then, on the other hand, I imagine the KallistoOS is similar to the PS2 community. Maybe centered around a dedicated forum so all potential developers can already discover this features availability via the forum.
So maybe it is a moot point.

KallistiOS has a maintained repository of add-on libraries. libsmb2 is included, so it's discoverable to our users.

We have vfs aswell for ps2, but it's wLaunchelf. i'm implementing for a fork of OPL It should be awesome port this guy to other platforms.

I have no objections.
If someone wants to make this into a general wrapper for embedded systems, I will not object to a PR.

It should be more easier than implementing usmb2 to opl for streaming games, i will take a look at it, when i have some time.
