Fix Requires parsing in CheckIfDepsDeprecated and CheckOwnDirs
    
    In case of rich deps, the return of dnf repoquery was garbage because of
    the non-closed parenthesis at the start of the query. It causes repoquery to
    return a list of *all* packages and thus took forever to run.
    In a similar manner, Rust packages with modular subpackages are not
    handled correctly by dnf repoquery, not returning any provides at all.
