Remove a useless post-install dependency on perl-macros from perl-interpreter
    
    Nowadays perl-interpreter is not presented in a minimal build root.
    Nowadays perl-interpreter means /usr/bin/perl executable only.
    When FPC approved new Perl guidelines it added perl-macros to the
    dependencies of perl-generators.
    
    Packages that do not depend on perl-generators will have to require
    perl-macros explicitly.
