deps: bump lief to 0.16.6

Some of the primary changes are:
- lief.EXE_FORMATS became lief.Binary.FORMATS IN 0.14.0
        - https://github.com/lief-project/LIEF/blob/494f116c6b8c9163fc4b5f6497233f18424981ee/doc/sphinx/changelog.rst?plain=1#L702
- lief.ARCHITECTURES became lief.Header.ARCHITECTURES in 0.16.0
        - https://github.com/lief-project/LIEF/blob/494f116c6b8c9163fc4b5f6497233f18424981ee/doc/sphinx/changelog.rst?plain=1#L226C18-L227C18
- lief.ELF.ARCH.x86_64 became lief.ELF.ARCH.X86_64

This commit includes a workaround for the bug fixed in
https://github.com/lief-project/LIEF/pull/1218, but the workaround can
be kept, since it makes `has_nx` checks stricter by enforcing both heap
and stack are non-executable.

This change also requires a patch to partially revert a commit to LIEF
(https://github.com/lief-project/LIEF/commit/f23ced2f4ffc170d0a6f40ff4a1bee575e3447cf)
which broke compatibility with versions of scikit-build-core <= 0.10.x.

This patch can be dropped once the guix time machine advances to or
beyond https://codeberg.org/guix/guix/commit/35c5f07e967155d2276c7ec58e5108e4da02c974,
which bumps the scikit-build-core version in guix from 0.9.3 to 0.10.7.
