tools/dwarves: add host package

dwarves is a set of tools that use the debugging information inserted in
ELF binaries by compilers such as GCC. Utilities in the dwarves suite
include pahole, which can be used to find alignment holes in structs and
classes, and also extracts other information such as CPU cacheline
alignment, helping pack those structures to achieve more cache hits.

These tools are also used to encode and read the BTF type information
format used with the bpf syscall, making this a Linux build dependency
when using kernel BTF information.
