perf hist: Improve srcfile sort key performance (really)

Browse Source 
The earlier commit f0cdde28fe ("perf hist: Improve srcfile sort
key performance") updated the srcfile logic but missed to change the
->cmp() callback which is called for every sample.

It should use the same logic like in the srcline to speed up the
processing because it'd return the same information repeatedly for the
same address.  The real processing will be done in
sort__srcfile_collapse().
