Amiga adf launch not working due to full path being written to tmp/LASTLAUNCH.mgl

[ByteMavericks]

Amiga ADFs aren't being inserted correctly by minimig core. The MGL file includes the full path (/media/fat/games/Amiga/xyz.adf) and the core doesn't support this. Removing the path and passing just the path relative to Amiga/ works.

Reproduction steps:

1. Have an ADF file in /media/fat/games/Amiga, eg wb13.adf
2. Write /Amiga/wb1.3.adf to token (via any means, I used Zaparoo app)
3. Attempt launch. The WB hand appears with the default settings for minimig, no disk is inserted
4. Copy /tmp/LASTLAUNCH.mgl to _Computer
5. Reattempt launch by selecting LASTLAUNCH from Computer menu on MisterFPGA. Same behaviour as 3 observed.
6. edit _Computer/LASTLAUNCH.mgl to remove full path from path entry (change /media/fat/games/Amiga/wb13.adf to wb13.adf)
7. Reattempt launch by selecting LASTLAUNCH from Computer menu
8. Success! Minimig launches with correct ADF file inserted info df0:
