Fix base path on Linux

[nvllsvm]

When the path is /usr/bin/nuked-sc55, the absolute path must be used to determine the correct base path of /usr/share/nuked-sc55.

Should be fine!
Going to test this soon.

Hm - it works fine for me, though I'm able to reproduce your error after removing read permissions from the *.bin files. Do you still get the error after adding read permissions to the rom files (sudo chmod +r *bin)?

$ pwd
/home/ar

Works perfectly fine on Debian
