Subject: [PATCH v2 4/5] perf tools: Fix alignment on some sort keys

The srcline, srcfile and trace sort keys can have long entries.  With
commit 89fee7094323 ("perf hists: Do column alignment on the format
iterator"), it now aligns output with hist_entry__snprintf_alignment().
So each (possibly long) sort entries don't need to do it themselves.
