FYI: really remove duplicate run paths

[Ralf Wildenhues]

Applied to HEAD (not present in branch-1-5).  This patch is pretty
obvious when looking at the code: it originated from the pieces below,
which deal with space-separated variables.  Due to the colon separation,
we now need to match with a colon as well.  The bug was harmless though,
most link editors will throw away the duplicate run path entry anyway.

Cheers,
Ralf

        * libltdl/config/ltmain.m4sh (func_mode_link): Fix matching
        duplicate run path entries with the correct separator.
