perf symbols: Encapsulate dsos list head into struct dsos
This is a precursor patch to enable long name searching of DSOs using
a rbtree.
In this patch, a new dsos structure is created which contains only a
list head structure for the moment.
The new dsos structure is used, in turn, in the machine structure for
the user_dsos and kernel_dsos fields.
Only the following 3 dsos functions are modified to accept the new dsos
structure parameter instead of list_head:
- dsos__add()
- dsos__find()
- __dsos__findnew()
