Set a default PATH if PATH is empty or unset
mount(1) unsets PATH before calling mount.fuse. Therefore it's not set in gocrpytfs either and daemonization fails if gocryptfs was not executed via an absolute path. mount.fuse handles this by leaving the execution of the helper to /bin/sh. /bin/sh handles an empty PATH by searching a few default locations. This patch sets the PATH to a sane default if it's empty or unset.
