locateVolatilityExecutable not trying on Linux

[HappyLer]

The function trying to locate the volatility executable does not try to locate it on linux but rather returns null and and error is thrown. Therefore this plugin should be disabled in Linux, the path should be configurable or the function should at least check the path.

I've changed the source to include a Linux path to volatility but the plugin fails, it's still in the experimental module so Linux support doesn't seem like the priority, though I'd be interested in knowing when it's supported
