    gnu: python-pybedtools: Update to 0.8.0 and fix build.
    
    From 40db2b4eae5ca61a3134cdaf7b156ed1ae9f7415 Mon Sep 17 00:00:00 2001

    Subject: [PATCH] gnu: python-pybedtools: Update to 0.8.0 and fix build.
    
    * gnu/packages/bioinformatics.scm (python-pybedtools): Update to 0.8.0.
    [phases]{disable-broken-tests}: Do not disable "test_issue_157" and
    "test_to_dataframe" tests.  Disable the "test_getting_example_beds".
    {remove-cython-generated-files}: Add phase.
    {generate-cython-extensions}: Add phase.
    {check}: Move from python2-pybedtools to here.  Add a scripts
    subdirectory of the build directory to the PATH, so that the tests can call
    them.  Invoke pytest rather than nosetests.
    [modules]: Move from python2-pybedtools to here.
    [propagated-inputs]: Depend on the current BEDTOOLS rather than version 
1.26.
    [native-inputs]: Replace python-nose by python-pytest and add python-psutil.
