Subject: [PATCH] net: drop NET dependency from HAVE_BPF_JIT

There is no point having the NET dependency on the select target,
as it forces all users to depend on NET to tell they support BPF_JIT.
Move the config option to the bottom of the file - this
could be a nice place also for future "selectable" config symbols.

Fix up all users to drop the dependency on NET now that
it is not required to supress warnings for non-NET builds.

Did a few "make ARCH=xxx allnoconfig" and no warning were triggered.

Do you want me to take this directly, or will it go through the net
tree? I can live with it either way.
