[Buildroot] [PATCH 01/29 v2] package/libsigrokdecode: needs python3 w/ zlib support

[Yann E. MORIN]

Some protocol decoders in libsigrokdecode need the zlib module:

    srd: ModuleNotFoundError: Failed to load decoder usb_power_delivery: import by name failed: No module named 'zlib'
    srd: Traceback (most recent call last):
      File "/usr/share/libsigrokdecode/decoders/usb_power_delivery/__init__.py", line 24, in <module>
        from .pd import *
      File "/usr/share/libsigrokdecode/decoders/usb_power_delivery/pd.py", line 24, in <module>
        import zlib   # for crc32
        ^^^^^^^^^^^
    ModuleNotFoundError: No module named 'zlib'
