python3: update 3.9.7 -> 3.10.0

native and target 0001-Lib-sysconfig.py-use-libdir-values-from-configuratio.patch
replaced by native-only 0001-Lib-sysconfig.py-use-prefix-value-from-build-configu.patch
which is more reboust against upstream changes, and keeps target code unmodified.

This however necessitated adding 0001-sysconfig.py-use-platlibdir-also-for-purelib.patch
to avoid hardcoding 'lib' on target builds as libdir.

Drop chunk from 0001-distutils-sysconfig-append-STAGING_LIBDIR-python-sys.patch as
upstream now uses sysconfig directly inside distutils.

Add 0001-Lib-pty.py-handle-stdin-I-O-errors-same-way-as-maste.patch and
0001-multiprocessing-disable-a-failing-test.patch to address ptest failures.

License-Update: copyright years, case corrections.

+Subject: [PATCH] Lib/pty.py: handle stdin I/O errors same way as master I/O
+ errors
+
+reading stdin can throw the same I/O errors as reading from master fd does,
+e.g. when running under Yocto's test harness:
+======================================================================
+ERROR: test_spawn_doesnt_hang (test.test_pty.PtyTest)
+----------------------------------------------------------------------
+Traceback (most recent call last):
+  File "/usr/lib/python3.10/test/test_pty.py", line 316, in test_spawn_doesnt_hang
+    pty.spawn([sys.executable, '-c', 'print("hi there")'])
+  File "/usr/lib/python3.10/pty.py", line 181, in spawn
+    _copy(master_fd, master_read, stdin_read)
+  File "/usr/lib/python3.10/pty.py", line 157, in _copy
+    data = stdin_read(STDIN_FILENO)
+  File "/usr/lib/python3.10/pty.py", line 132, in _read
+    return os.read(fd, 1024)
+OSError: [Errno 5] Input/output error
+
+So let's treat both channels the same.
