module/module-base/lttng-modules: Improve kernel module dependencies

If we have DEPENDS = "virtual/kernel" is means that the kernel module
depends on the kernel's do_populate_sysroot task. This is not entirely
desireable since that depends on do_install which depends on
do_compile_kernelmodules and so on. In a situation where rm_work in involved
this can cause some pretty length build cycles after the kernel workdir
has been cleaned up by rm_work.

As well as removing this, take the opportunity to clean up duplicated
dependency lines, tweak the dependency of make_scripts for the same
reason and generally try and make things more readable.
