perf tools: Add dso__data_get/put_fd()
Using dso__data_fd() in multi-thread environment is not safe since
returned fd can be closed and/or reused anytime.
So convert it to the dso__data_get/put_fd() pair to protect the access
with lock.
The original dso__data_fd() is deprecated and kept only for testing.
