Ship full CPython (python3) for a full-featured guest python#7
Merged
Conversation
The guest needs a full-featured Python: the migrated test suite (and real debugging use) requires ctypes (FFI for libc calls / ioctl), mmap, fcntl, socket, ssl, sqlite3 -- none of which python3Minimal builds. Switch to the full python3 interpreter. Verified x86_64: lib-dynload now includes _ctypes, fcntl, mmap, _socket, _ssl, _sqlite3 (77 modules vs 63), and the bundle still passes the runtime link-closure check (the new libs are staged into dylibs).

hyperfs (which provided /igloo/utils/micropython) is gone, so the 9 tests
that used it now run on penguin-tools' CPython at /igloo/utils/python3:
- uos -> os; usocket -> socket
- ffilib/uctypes mmap -> the CPython `mmap` module (native_mmap, devfs
mmap_custom, pseudofile_mmap_{shared,private,rw})
- ffilib open/ioctl -> os.open + fcntl.ioctl (pseudofiles_comprehensive)
- ffi libc/lib_inject calls -> ctypes (uprobes, proc_mtd_dynamic)
Requires the full CPython (ctypes/mmap/fcntl/socket), so bump
PENGUIN_TOOLS_VERSION to 0.0.6 (rehosting/penguin-tools#7).
