dev-python/pyramid: Fix deps, enable tests

Correct the package dependencies, and enable tests. The former includes:

1. putting dev-python/setuptools in RDEPEND since the package uses
   entry_points (pkg_resources),

2. adding dev-python/zope-deprecation to RDEPEND since the package
   states that as a runtime dependency,

3. removing nose & coverage from test dependencies since they are not
   used for testing upstream (it is extra dep for post-install testing
   but setup.py and the tests use plain unittest),

4. adding missing py2-conditional dependency on dev-python/zope-component
   for tests.

Appropriately switch python_test() to use 'setup.py test'.
