perf tools: Add a "dso_size" sort order
Add DSO size to perf report/top sort output list.
This includes adding a map__size fn to map.h, which is
approximately equal to the DSO data file_size:
DSO file size map (end-start) file / (end-start)
libwebkit2gtk-4.0.so.37.24.9 43260072 41295872 95%

Sample output:
$ ./perf report -s dso_size,dso
