devtools: Correctly extract symbol versions in symbol-check

Summary

devtools: Fix verneed section parsing in pixie

I misunderstood the ELF specification for version symbols (verneed):
The vn_aux pointer is relative to the main verneed record, not the
start of the section.

This caused many symbols to not be versioned properly in the return
value of elf.dyn_symbols. This was discovered in #21454.

Fix it by correcting the offset computation.

devtools: Add xkb version to symbol-check

xkb versions symbols (using the prefix V), as this library is used by
bitcoin-qt, add it to the valid versions in symbol-check.py.

devtools: Integrate ARCH_MIN_GLIBC_VER table into MAX_VERSIONS in symbol-check.py

The (ancient) versions specified here were deceptive. Entries older than
MAX_VERSIONS['GLIBC'], which is 2.17, are ignored here. So reorganize
the code to avoid confusion for other people reading this code.

This is a backport of core#22244
Depends on D13962 and D13973

Test Plan

gitian builds

run the guix build for x86_64 linux (which now shows errors in symbol check)

You're missing the comment from the source material.
Without the comment this is impossible to understand. With the comment it's "only" cryptic.
