tools/dwarves: update to v1.27
Update to the latest upstream version and add a patch that enables pahole
reproducible builds if SOURCE_DATE_EPOCH is defined in the environment.

This patch helps avoid BTF-related module loading problems with packages
built separately from the kernel such as mac80211 or kselftests-bpf, e.g.:

bab3ae2ee7 tools: prefer gz or bz2 tarballs
In the light of recent XZ events, and fundamental XZ issues lets work on
moving away from using XZ.

So, use gz compressed tarballs as sources whenever possible.

dwarves only offers bz2 compressed tarballs, so use those as size
difference is minor compared to XZ.

02850d7c9c 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.
