Add procfs fallback for figuring out the cwd
Opening a terminal or file manager window requires weltschmerz to know the current working directory. At the moment weltschmerz relies on the application being run in the terminal to generate OSC 7 codes that specify the path. However, OSC 7 is not yet widely supported by default, and the VTE terminal emulation layer, which manages the OSC 7 path state for weltschmerz, will overwrite local paths with ones that point to a remote computer if an OSC 7 enabled application is run under ssh. This change adds a fallback that uses the symlink to current working directory located at /proc/<child pid>/cwd. On Linux this method should always work and was how these features were implemented before adoption of OSC 7. The procfs method is used as a fallback instead of the primary method since it can only see the working directory changes of the direct child process.
