perf annotate: Avoid reallocation in objdump parsing
Objdump output is parsed using getline which allocates memory for the
read. Getline will realloc if the memory is too small, but currently the
line is always freed after the call.
Simplify parse_objdump_line by performing the reading in symbol__disassemble.
