m_debuginfo/debuginfo.c VG_(get_fnname_kind) _start is below main
With glibc 2.34 we might see the _start symbol as the frame that
called main instead of directly after __libc_start_main or
generic_start_main.
Fixes memcheck/tests/badjump[2], memcheck/tests/origin4-many,
helgrind/tests/tc04_free_lock, helgrind/tests/tc09_bad_unlock
and helgrind/tests/tc20_verifywrap.
