perf symbols: Remove open coded management of short_name_allocated member

Instead of expecting callers to set this member accodingly so that later
at dso destruction it can, if needed, be correctly free()d, make it a
requirement by passing it as a parameter to dso__set_short_name.

[ Renamed the 'allocated' parameter to clearly indicate to which variable it refers to. ]
