package/gnuradio: fix gnuradio python libraries for cross-compile

Browse Source 
By default, module libraries have a suffix based on cpython version + host
architecture: this is fine for a native compile when these libraries are used on
the same computer (or similar computers). But when target architecture is not
the same python is unable to find libraries due to the wrong suffix and produces
unclear errors messages:

# python3
Python 3.11.3 (main, Jun 19 2023, 14:15:44) [GCC 11.4.0] on linux
Type "help", "copyright", "credits" or "license" for more information.
>>> from gnuradio import blocks
Traceback (most recent call last):
  File "/home/xxx/buildroot/output/build/gnuradio-3.10.4.0/gr-blocks/python/blocks/__init__.py", line 18, in <module>
ModuleNotFoundError: No module named 'gnuradio.blocks.blocks_python'

During handling of the above exception, another exception occurred:

Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "/home/xxx/buildroot/output/build/gnuradio-3.10.4.0/gr-blocks/python/blocks/__init__.py", line 22, in <module>
ModuleNotFoundError: No module named 'gnuradio.blocks.blocks_python'
>>>

By adding _PYTHON_SYSCONFIGDATA_NAME="$(PKG_PYTHON_SYSCONFIGDATA_NAME)" at configure time, sysconfig will
return correct informations (target architecture) instead of host architecture.
