run_tests.sh compilemessages should remove English MO files

[Akihiro Motoki]

Django manage.py compilemessage comple message catalogs of all languages including English (source language) by default and there is no way to exclude a specific language. English is a source language in Horizon and there is no need to have compiled message catalog (MO files) for English. After running run_tests.sh --compilemessages, we always have unnecessary English MO files and we need to remove it manually every time :-(
run_tests.sh --compilemessages should remove English MO files.

For long term solution, it seems better to add an option to exclude a specific language to "./manage.py compilemessages".

    ./run_tests.sh --compilemessages compiles all languages including
    English, but English is the source language and there is no need
    to have compiled message catalogs for English.

    Also this commit update the description of --makemessages.
