perf tools: Compare dso's also when comparing symbols
Linus reported that sometimes 'perf report -s symbol' exits without any
message on TUI. David and Jiri found that it's because it failed to add
a hist entry due to an invalid symbol length.
It turns out that sorting by symbol (address) was broken since it only
compares symbol addresses. The symbol address is a relative address
within a dso thus just checking its address can result in merging
unrelated symbols together. Fix it by checking dso before comparing
symbol address.
