Bump Python from 3.10.11 to 3.13.14, the latest maintenance release of
the 3.13 series.

Patches:
- Drop patch 0000 (undefine HAVE_FORK/HAVE_EXECVE): the macros no longer
  come from posixmodule.c in 3.13 and the port's own pyconfig.h already
  disables both
- Rewrite patch 0001 (asyncio): 3.13 imports os upstream, only io needs
  to be added
- Rewrite patches 0002 and 0003 (library install): Makefile.pre.in was
  restructured, the compileall invocations were consolidated and the
  libinstall target now depends on all rather than build_all
- Add patch 0005: faulthandler.c uses Py_ARRAY_LENGTH in a static
  initializer, which does not compile as the macro expands to a comma
  expression under C11

Sources:
- Update paths for files reorganized upstream: Parser/tokenizer.c was
  split across Parser/lexer/ and Parser/tokenizer/, Modules/_sre.c moved
  to Modules/_sre/sre.c, the sha256 and sha512 modules were unified into
  sha2module.c, and _sha3/sha3module.c moved to Modules/
- Add the sources introduced in 3.13, including the new lock and garbage
  collection implementations, the split compiler pipeline, and the HACL*
  hashing sources
- Remove sources deleted upstream and the test-only modules

Build configuration:
- Add a UK_PREPARE rule to generate the frozen module headers, which
  CPython produces during its own build
- Add the source root, compiler and HACL* include paths, and define
  PLATLIBDIR for getpath
- Remove the configure-generated pyconfig.h so the port's own header is
  used
- Define HAVE_NETDB_H and HAVE_GETHOSTBYNAME: Unikraft builds with
  -U __linux__, which makes socketmodule.c undefine HAVE_GETHOSTBYNAME_R
  and leave sock_decode_hostname out while it is still referenced

Housekeeping:
- Regenerate _sysconfigdata.py, which was generated for 3.7
- Sync Library.uk, which declared 3.7.4

Tested on qemu/x86_64 with catalog-core/python3-hello: the unikernel
builds, boots and runs hello.py.
