Subject: [PATCH 08/41] perf tools: Fix missing label symbols

label symbols are missing because elf_sec__is_a() fails
to find the section because the section strings do not
match the section headers because the sections headers
are from the 'runtime' object and the sections strings
are from the 'symbol source' object.

Fix by getting the section strings from the 'runtime'
object so that they match the section headers.
