standalone binary raises error when compiled on a newer version of Linux

```
./scanner
[9662] Error loading Python lib '/tmp/_MEI9HTRtJ/libpython3.10.so.1.0': dlopen: /lib/x86_64-linux-gnu/libc.so.6: version `GLIBC_2.33' not found (required by /tmp/_MEI9HTRtJ/libpython3.10.so.1.0)
```
Based on [this](https://github.com/pyinstaller/pyinstaller/wiki/FAQ#gnulinux), we need to build gcp_scanner on an older system than we plan to use it on. We could also add support for [StaticX](https://github.com/JonathonReinhart/staticx/).
