kernel/modules: kmod-sched: add some common, useful actions

Add act_pedit, act_csum, act_gact and act_simple modules for additional
tc action support. Module act_simple helps with debug and logging, similar
to iptables LOG target, while act_gact provides common generic actions.
Modules act_pedit and act_csum support general packet mangling, and have
been the subject of feature requests and forum discussions (e.g. DSCP),
as well as being added to the Turris OS fork of OpenWrt ~2 years ago.

Also select dependency kmod-lib-crc32c to support act_csum.
