fix(redbear-bare): enable bare target to build and boot

Multiple fixes to make redbear-bare actually build and progress
through boot:

config/redbear-bare.toml:
- filesystem_size: 96 -> 192 MiB. The bare image packages ~153 MiB
  of installed content (zsh, base, base-initfs, kernel, relibc,
  userutils, libgcc, libstdcxx, plus coreutils/extrautils/etc.),
  so 96 MiB triggers installer ENOSPC during commit.
- Override 31_debug_console.service with postinstall=true so the
  override wins over minimal.toml's version that uses
  /scheme/debug/no-preserve (which busy-loops when the debug
  scheme returns ENODEV in the bare initfs).

recipes/core/base-initfs/recipe.toml:
- bare_initfs() now only references BINS in the base workspace
  (init, logd, ramfs, randd, zerod, ptyd). getty is removed from
  BINS because it lives in userutils, not base.
- Copy getty from the sysroot into the initfs after the cargo
  build (analogous to the existing redoxfs/ion/driver-manager
  sysroot copies).
- Filter the init.d copy under REDBEAR_BARE_INITFS to keep only
  services for binaries we actually built (logd, randd, zerod,
  runtime.target, ramfs@.service, 90_initfs.target, 50_rootfs).
  The mainline 23 services reference fbcond/vesad/acpid/pcid/
  fbbootlogd/hwd/inputd which aren't in the bare BINS, so
  init would try to start them and busy-loop.
- Synthesize minimal 00_ptyd.service and 30_getty.service units
  in the initfs since they're built/copied but not in the
  mainline init.initfs.d.
- Override 00_runtime.target to add ptyd and getty as weak
  requires (the mainline target references nulld/rtcd which we
  filtered out).
