maps may belong to >1 thread. In contexts like symbolization information from the thread may be useful, such as the ELF machine. As the maps can be gained from the thread switch from holding maps in struct map_symbol to holding the thread. Holding the maps in addr_location is also redundant, switch this to using thread__maps.
