perf symbols: Export elf_section_by_name and reuse
Remove duplicated elf_section_by_name() functions from unwind.c and probe-event.c and use one exported elf_section_by_name() instance defined in symbol-elf.c. Note that this also moves get_text_start_address() to merge HAVE_DWARF_SUPPORT defined area.
