unit-test: Add debug symbols for common packages

Valgrind and gdb produce much more useful output if we install the debug
symbols for the libraries we commonly use in our code. This is useful
for manual testing but is especially useful for the newly added valgrind
automation.

Tested:
    Works on artful which doesn't provide dbgsym keys and falls back to
    the manual fetch. Works on bionic which uses the built-in dbgsym
    keys. Debug symbols now show up in valgrind logs when testing
    sdbusplus.
