perf hist: fix objdump output parsing
hist_entry__annotate() runs objdump with -S option so the output may contain
lines of any format. If a line starts with a colon strtoull() returns 0 and
calculated offset will be negative. This causes perf annotate segfaults.
Make sure that strtoull() has parsed at least one digit.
