distutils-r1.eclass: Fix subphase return value passthrough

Fix distutils-r1 phase functions to correctly pass through the return
value from the subphases.  This fixes e.g. the mistake of virtx
not failing in the following case:

    src_test() {
        virtx distutils-r1_src_test
    }

    python_test() {
        epytest
    }

This is because virtx implicitly uses nonfatal and epytest uses
`die -n`.  However, since the return value was not passed through, virtx
never knew that anything has failed.

While this covers only trivial cases and this is better solved via dying
explicitly in the redefined python_test(), there's no harm in adding
this passthrough.
