Building lxc with glibc 2.43 fails due to stricter header checks and
FORTIFY related validations.

Backport the following upstream fixes to resolve these build failures:
  - meson.build: fix open_how include handling for glibc 2.43+
  - meson.build: fix openat2 include typo exposed by glibc 2.43 + FORTIFY
