linux: Modify kernel configuration to fix runqlat issue

Browse Source 
In Qemu Running "/usr/share/bcc/tools/runqlat 1 5" gives following error:-

libbpf: kernel BTF is missing at '/sys/kernel/btf/vmlinux', was CONFIG_DEBUG_INFO_BTF enabled?
libbpf: failed to find valid kernel BTF
modprobe: FATAL: Module kheaders not found in directory /lib/modules/6.10.14-yocto-standard
Unable to find kernel headers. Try rebuilding kernel with CONFIG_IKHEADERS=m (module) or installing
the kernel development package for your running kernel version.
chdir(/lib/modules/6.10.14-yocto-standard/build): No such file or directory
Traceback (most recent call last):
  File "/usr/share/bcc/tools/./runqlat", line 293, in <module>
    b = BPF(text=bpf_text)
  File "/usr/lib/python3.13/site-packages/bcc/__init__.py", line 479, in __init__
    raise Exception("Failed to compile BPF module %s" % (src_file or "<text>"))

the following patch fixes the error.
