changed do_repos() to filter out disabled repos of a package

Changed do_repos() to filter out disabled repos of a package. Read
package from checked out package dir. This changes also the output
of getbinaries if args are missing and the user is within a checked
out package dir. Show only enabled repos in this case.

Allow also osc repos [PROJECT] [PACKAGE].
