[gimp] INSTALL: make clear not to install libmypaint from master.

commit 1806e56405cb0579f521a27d71c00aa417d27d32

    INSTALL: make clear not to install libmypaint from master.
    
    Also add a note about installing possibly from the release tarball or
    from the package manager of a distribution, since apparently some assume
    it has to be installed from repository, making their own life harder
    that it has to!
    Finally split the libmypaint and mypaint-brushes into their own numbers
    to make things even clearer.
