texlive-1.0.tcl: fix installation with -doc variant (#25329):

  * remove dependencies on texlive-documentation-* ports when -doc is
    specified

  * install a file in $prefix/share/doc/texlive containing the list of
    TeX packages installed by each texmf port. Besides being
    ostensibly useful information, this keeps MacPorts from erroring
    out if no other files were installed
