Look for the DSP ROM files in Sys/GC as before before trying User/GC

to allow both system-side (also Windows) and per-user installations.

The IPL ROM is another candidate for this, but I don't have an
image to test with.

Perhaps a more general solution would be to just phase out the Sys
directory. As used for data which would have been available in ROM
or flash on the real hardware, it really contains two classes of
files that are both read-only during emulation:

- Settings and font files, which can be freely distributed
- ROM files which must be obtained from the user's own GC or Wii

Since the two could be freely put together on Windows without any
problems and with the users of that platform being resistant to
change, it may be easiest to just treat Sys as another directory
to be copied from the application bundle into User/Sys at startup
on non-Windows.
