DEB package installs its libraries under /usr/local/lib

**Expectation**

Library packages install their files into normal system locations, like the other Intel driver stack packages, e.g. under `/usr/lib/x86_64-linux-gnu/` on Ubuntu 24.04.

**Actual**
```
$ dpkg -L intel-igc-core-2
/usr
/usr/local
/usr/local/lib
/usr/local/lib/igc2
/usr/local/lib/igc2/NOTICES.txt
/usr/local/lib/libiga64.so.2.34.4+1778234987
/usr/local/lib/libigc.so.2.34.4+1778234987
/usr/local/lib/libiga64.so.2
/usr/local/lib/libigc.so.2
```

(This is from a package downloaded from the releases page in this repo, not from Intel package repos, in case those are packaged differently.)
