linux-kernel config: disable DEBUG_INFO_REDUCED

Browse Source 
Linux's aarch64 defconfig has been updated in 5.13 to enable "reduced"
debug infos (upstream commit ed938a4bfc58 ("arm64: defconfig: Use
DEBUG_INFO_REDUCED"), but that commits locks DEBUG_INFO_BTF as noticed
in #175467

This disables it back which should fix bpftrace usage of BTF not working
on newer kernels.
