[Buildroot] [PATCH 1/1] package/libsigrokdecode: fix build with python 3.9

[Fabrice Fontaine]

This will fix the following build failure with python 3.9 and
sigrok-cli:

/srv/storage/autobuild/run/instance-1/output-1/host/opt/ext-toolchain/bin/../lib/gcc/mips64el-buildroot-linux-uclibc/5.5.0/../../../../mips64el-buildroot-linux-uclibc/bin/ld: /srv/storage/autobuild/run/instance-1/output-1/host/bin/../mips64el-buildroot-linux-uclibc/sysroot/usr/lib/libsigrokdecode.so: undefined reference to `PyList_Insert'

Fixes:
