import-checker: exclude mercurial packages installed into the system path

If mercurial was installed into a directory other than the site-packages,
test-module-imports.t failed as 'mercurial.node' was listed in stdlib_modules:

  testpackage/latesymbolimport.py relative import of stdlib module

Instead, we should exclude our packages explicitly.
