Fix bug that causes status line to be empty if Unix username has spaces

[joschnitzbauer]

The current implementation for extracting the current working directory (cwd) fails for Unix when the username has a space. This causes the cwd string to be empty, which leads to a completely empty status line.

Specifically, awk retrieves the 4th field from the lsof output, but when the username has a space, cwd is actually the 5th, because of the additional whitespace.

The submitted patch circumvents this by using the -F option for lsof so that columns are returned as rows for increased machine-readability. The correct field is filtered by process id (-p ${pid}) and field identifier (-d cwd), where the -a option ensures the logical and of these filters. The output of lsof is then grepped to get the field with identifier n (name) as the first character. This identifier is finally removed with cut, so that the remaining string is the current working directory.

Tested with Hyper 2.0.0 on MacOS High Sierra 10.13.6
