uncovered: list uncovered python modules

This bash script prints list of modules uncovered by oe-selftest
or any other test that produces coverage report.

It expects coverage report on its stdin and a directory to look
for python modules as a command line parameter, e.g.
    coverage report --rcfile=build/.coveragerc | ./scripts/contrib/uncovered bitbake/
should print list of uncovered python modules from bitbake/
directory tree to stdout.
