dev-python/pytest-timeout: Remove RDEP on pytest

Do not explicitly RDEPEND on dev-python/pytest.  It is a pytest plugin,
so it will only be used by pytest itself (which will obviously
be installed then), and having the dep may unnecessarily force pytest
downgrade for Python 2.7.  There is a little harm in having this package
installed unnecessarily for py2.7.
