[PATCH uci 2/2] CI: Add github action

[Hauke Mehrtens]

Add a github action to build uci and then execute the tests.

This first builds and installs libubox and then uses that dependency to
build and test uci.

clang 14 generates debug information in DWARF 5 format, but valgrind
19.0 does not support that. Install valgrind 20.0 from experimental
which supports it.
