tools: Copy hashtable.h into tools directory
Copy hashtable.h from include/linux/tools.h. It's needed by objtool in
the next patch in the series.
Add some includes that it needs, and remove references to
kernel-specific features like RCU and __read_mostly.
Also change some if its dependency headers' includes to use quotes
instead of brackets so gcc can find them.
