btf: require pahole 1.21+ for DEBUG_INFO_BTF with default DWARF version
As described in commit 42d9b379e3e1 ("lib/Kconfig.debug: Allow BTF +
DWARF5 with pahole 1.21+"), the combination of CONFIG_DEBUG_INFO_BTF
and CONFIG_DEBUG_INFO_DWARF5 requires pahole 1.21+.
GCC 11+ and Clang 14+ default to DWARF 5 when the -g flag is passed.
For the same reason, the combination of CONFIG_DEBUG_INFO_BTF and
CONFIG_DEBUG_INFO_DWARF_TOOLCHAIN_DEFAULT is also likely to require
pahole 1.21+ these days. (At least, it is uncertain whether the actual
requirement is pahole 1.16+ or 1.21+.)
