Building rostrum for source requires on ubuntu 20.04 requires the installation of the following to packages:

• llvm
• libclang-dev

To avoid the following error:

The same fix has been deployed for 2 other projects via the following MRs:

• https://gitlab.com/nexa/docker-nexa/-/merge_requests/15
• https://gitlab.com/nexa/rostrum/-/merge_requests/381/diffs#6651ddff6eb82c840ced7c1dddee15c6e1913dd4_3_3

This fix out-of-the-tree and gitian build process.
