tools lib api fs: Move debugfs__strerror_open into tracing_path.c object

Moving debugfs__strerror_open out of api/fs/debugfs.c, because it's not
debugfs specific. It'll be changed to consider tracefs mount as well in
following patches.

Renaming it into tracing_path__strerror_open_tp to fit into the
namespace. No functional change is intended.
