`go_path` of goose.toml is not used to set `-dir` for goose

[marshtompsxd]

Instead, the dir of the config path is used to set -dir for goose: https://github.com/mit-pdos/perennial-cli/blob/main/cmd/goose.go#L69

Is this expected behavior? Seems that go_path is not actually used except in findGoPath

Fixed by #3 - thanks for the report!
