This fixes the compilation when we have sysprofd fully disabled.
That is not an ideal configuration, but keeping it working
ensures that some of the code is easy copy/paste'able in the
future for some situations.
We don't want to avoid adding the symbols to the index table, or we will
get the wrong addresses.
So instead, add them, and then ignore the symbols upon lookup.
This allows us to pass in the file to read from, and adds a quick test
case to view the parsed output. It also fixes a base-10 vs base-16
mistake in parsing addresses.
If we have a system where we can read kallsyms without elevated
privilledges do that. Otherwise, query the sysprod daemon to get the
available kernel symbols.
The lib/ directory was getting a bit out of hand, so this tries
to organize things a bit so it is easier going forward to locate
the code people want to patch.
