import-checker: don't treat modules as relative one if not found

The previous patch ensures all module names are recorded in `imports`
as absolute names, so we no longer need to treat modules as ones
imported relatively from the target source if they appear to not be
from the stdlib.

import os

if os.environ.get('COVERAGE_PROCESS_START'):
    try:
        import coverage
        import random

        # uuid is better, but not available in Python 2.4.
        covpath = os.path.join(os.environ['COVERAGE_DIR'],
                               'cov.%s' % random.randrange(0, 1000000000000))
        cov = coverage.coverage(data_file=covpath, auto_data=True)
        cov._warn_no_data = False
        cov._warn_unimported_source = False
        cov.start()
    except ImportError:
        pass
