Nathan Chancellor 0c168d7f36 lib/Kconfig.debug: Allow BTF + DWARF5 with pahole 1.21+ ...

commit 42d9b379e3 upstream.

Commit 98cd6f521f ("Kconfig: allow explicit opt in to DWARF v5")
prevented CONFIG_DEBUG_INFO_DWARF5 from being selected when
CONFIG_DEBUG_INFO_BTF is enabled because pahole had issues with clang's
DWARF5 info. This was resolved by [1], which is in pahole v1.21.

Allow DEBUG_INFO_DWARF5 to be selected with DEBUG_INFO_BTF when using
pahole v1.21 or newer.
