[PATCH 0/2] Bring includes in linux/kmod.h up to date

The usermode helper declarations were previously provided by linux/kmod.h
but commit c1f3fa2a4fde ("kmod: split off umh headers into its own file")
moved them to linux/umh.h in 2017. Add explicit includes of linux/umh.h to
files that use usermode helpers and remove linux/kmod.h where it is no
longer needed.

Then clean up linux/kmod.h so that it includes only the headers that it
actually requires, importantly removing the compat linux/umh.h include.

Apologies for the wide distribution.

This cleanup is motivated by trying to reduce the preprocessed size of
linux/module.h, which includes linux/kmod.h. The linux/module.h header is
included by every *.mod.c file to provide `struct module` and other related
definitions, so it should avoid pulling in unnecessary dependencies. Note
that this series doesn't immediately improve the situation, since most of
the files included by linux/kmod.h are, for now, also included by
linux/module.h through other paths.
