perf symbols: Set module info when build-id event found

Browse Source 
Like machine__findnew_module_dso(), it should set necessary info for
kernel modules to find symbol info from the file.  Factor out
dso__set_module_info() to do it.

This is needed for dso__needs_decompress() to detect such DSOs.
