tracing: create trace2line
...
This lead to a re-factoring of count boot instructions, since trace2line
relies on the same tracing mechanism.
Also, now that we have common factored, I've decided to put the traces on
the out dir, to concentrate all outputs in a single place, and allow
easy switching between archs.

Disable networking at runtime with lkmc_nonet cli instead of build
...
This is necessary because qemu and gem5 now use the same build folder.
Separate ./run -e and -f for kernel options before and after the ' - '.
This was already the better thing to do when -E was introduced,
but lkmc_nonet prompted me to do it nicer now.
Use the common script to find the out_dir on every toplevel script.
Include usage man pages on README.
