RFC PATCH: debuginfod client doc tweak

commit c4726913b7766634cc5d8a97624e1b4708452d73 (HEAD -> master)
Author: Frank Ch. Eigler <fche@redhat.com>

    man debuginfod-client-config.7: Elaborate $DEBUGINFOD_URLS
    
    Add reference to /etc/profile.d and /etc/debuginfod/*.urls as possible
    source of default.  (No need to autoconf @prefix@ it, these paths are
    customarily distro standard rather than elfutils configurables.)
    Drop warning about federation loops, due to protection via PR27917 (0.186).
