This is necessary for the following: - to make sure os/exec can be imported - to make sure internal/testenv can be imported The internal/testenv package (which imports os/exec) is used by a lot of tests. By adding support for it, more tests can be run. This commit adds a bunch of new packages that now pass all tests.
