mailmap-update.sh sorts .mailmap with the caller's locale collation, so
the order of its entries depends on who runs the sync: e.g., with
en_US.UTF-8 vs C.UTF-8 (the default on GitHub runners). Syncs done in
different environments would keep reordering the file.
Always sort with LC_ALL=C.

The kernel repository has a .mailmap file to remap author names and
email addresses to their desired format in Git logs (for details, see
gitmailmap documentation [0]). Alas, this is only visible for author
information when looking at the logs locally, as GitHub does not support
mailmaps at the moment [1].
This commit adds a .mailmap file for libbpf, automatically generated
from the kernel's version. The script to generate the .mailmap is added,
too: it works by grepping email addresses from authors in the
repository, and collecting all lines ending with this address in the
kernel's .mailmap - in other words, all lines where this address is used
as a pattern for a remapping.
To keep the .mailmap up-to-date, add a call to the script to
sync-kernel.sh.
