perf report: Left align dynamic entries in hierarchy

Browse source

The dynamic entries are right-aligned unlike other entries since it
usually has numeric value.  But for the hierarchy mode, left alignment
is more appropriate IMHO.  Also trim spaces on the left so that we can
easily identify the hierarchy.

Before:

  $ perf report --hierarchy -i perf.data.kmem -s gfp_flags,ptr,bytes_req --stdio -g none

  # ..............  .................................................................................................
