objtool: Fix find_{symbol,func}_containing()
[ Upstream commit 5da6aea375cde499fdfac3cde4f26df4a840eb9f ]
The current find_{symbol,func}_containing() functions are broken in
the face of overlapping symbols, exactly the case that is needed for a
new ibt/endbr supression.
Import interval_tree_generic.h into the tools tree and convert the
symbol tree to an interval tree to support proper range stabs.
