Kim Phillips b74d12d598 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%
  libglib-2.0.so.0.5400.1		 1125680	 1118208	99%
  libc-2.26.so			 1960656 	 1925120	101%
  libdbus-1.so.3.14.13		  309456 	  303104	102%

Sample output:

  $ ./perf report -s dso_size,dso
  Samples: 2K of event 'cycles:uppp', Event count (approx.): 128373340
  Overhead  DSO size  Shared Object
    90.62%   unknown  [unknown]

Committer testing:

To sort by DSO size, use:

  # perf report -F dso_size,dso,overhead -s dso_size
