python3-maturin: Fix cross compilation issue for armv7l, mips64, ppc

When bitbaking python3-rpds-py it built extension module as:

  site-packages/rpds/rpds.cpython-312-armv7l-linux-gnueabihf.so

Which caused error on target:

  root@qemuarm:~# python3 -c "from rpds import HashTrieMap, HashTrieSet, List"
  Traceback (most recent call last):
    File "<string>", line 1, in <module>
    File "/usr/lib/python3.12/site-packages/rpds/__init__.py", line 1, in <module>
      from .rpds import *
  ModuleNotFoundError: No module named 'rpds.rpds'

Where as it should have been:

  site-packages/rpds/rpds.cpython-312-arm-linux-gnueabihf.so

+Subject: [PATCH 2/5] Fix cross compilation issue with linux-armv7l
+ architecture
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+When compiling under Yocto project for linux-armv7l target architecture
+.so files were generated incorrectly as:
+
+  rpds.cpython-312-armv7l-linux-gnueabihf.so
+
+Where as platform and EXT_SUFFIX are defined as:
+
+  >>> sysconfig.get_platform()
+  'linux-armv7l'
+  >>> sysconfig.get_config_vars()['EXT_SUFFIX']
+  '.cpython-312-arm-linux-gnueabihf.so'
+
+Which should have caused the .so files as:
+
+  rpds.cpython-312-arm-linux-gnueabihf.so
+
+Upstream-Status: Backport [https://github.com/PyO3/maturin/commit/0c6b8cc84eff72ed21098029aaba079b899dbee2]
