update versions for scalasca and related tools (#3697)

- clean up fetch urls

- inherit from AutotoolsPackage instead of Package

- explicit fPIC flags look suspicious, but leave them in there.

- in scalasca, use the cube version that is implicit from
  the scorep dependency instead of specifying it twice.
