vasilito 48a924c561 recipes: regenerate Cargo.lock for the 0.3.2 fork versions
The libredox 0.1.19 / redox_syscall 0.9.1 bump left 45 recipe lockfiles
pinning libredox 0.1.18+rb0.3.1 and redox_syscall 0.9.0+rb0.3.1. The
cookbook builds with --locked, so every affected recipe died with

  error: cannot update the lock file .../Cargo.lock because --locked was
  passed to prevent this

which is what took out redox-driver-sys -- and with it every Red Bear
driver -- during the redbear-full build. Regenerating the fork lockfiles
was not enough; the recipes that consume the forks as path deps carry
their own. This is step 6 of local/docs/FORK-BUMP-PATCHING-POLICY.md
applied to the recipe layer.

Also drop the hardcoded GCC version in recipes/libs/libstdcxx-v3: the
literal include/c++/13.2.0 stopped resolving the moment the cross
toolchain moved to 16.1.0, leaving -I pointing at a directory that does
not exist. Now resolves the newest installed C++ header directory and
fails loudly if there is none. Same failure class as the hardcoded
13.2.0 in mk/prefix.mk.

Note: a few recipe-level Cargo.lock files (redox-driver-pci, cpufreqd,
redbear-acmd/-ecmd/-ftdi) sit beside a recipe.toml whose [source] is
path = "source", so they are not build inputs; redox-driver-pci's even
references a redox-driver-core/Cargo.toml that does not exist. They are
left alone rather than given meaning they do not have.

redox-driver-sys now cooks clean.
