    libdw: dwarf_getsrcfiles should not imply dwarf_getsrclines

    dwarf_getsrcfiles causes line data to be read in addition to file data.
    This is wasteful for programs which only need file or directory names.
    Debuginfod server is one such example.

    Fix this by moving the srcfile reading in read_srclines into a separate
    function read_srcfiles.  This change improves debuginfod server's max
    resident set size by up to 75% during rpm indexing.
