vgm2wav won't find yrw801.rom unless it is in cwd

[sdsnatcher73]

If you have a vgm file with OPL4 chip, vgmplay will load yrw801.rom if it is located in /usr/local/share/vgmplay or ~/.config/vgmplay but vgm2wav (and possibly vgm2pcm) will report:
Warning! OPL4 Sample ROM (yrw801.rom) not found!
if you put the yrw801.rom in the same dir as the vgm file and run vgm2wav in that dir it will load the samples.

Good catch!

The reason it doesn't work is, that vgm2pcm/vgm2wav don't initialize the search paths. (VGMPlay does it in this rather large code block.) In that case, it will only search in the current directory.
