objtool: Move objtool_file struct off the stack
Objtool uses over 512k of stack, thanks to the hash table embedded in
the objtool_file struct. This causes an unnecessarily large stack
allocation and breaks users with low stack limits.
Move the struct off the stack.
Fixes: 042ba73fe7eb ("objtool: Add several performance improvements")
