tc: bash-completion: Add support for filter actions

Browse Source 
Previously, the autocomplete routine did not complete actions after a
filter keyword, for example:

$ tc filter add dev eth0 u32 [...] action <TAB>

did not suggest the actions list, and:

$ tc filter add dev eth0 u32 [...] action mirred <TAB>

did not suggest the specific mirred parameters. Add the support for this
kind of completion by adding the _tc_filter_action_options routine and
invoking it from inside _tc_filter_options.
