* Correct Jamfile to match Seacas's CMake Library Names

Jamfile change for Sierra's build system to support a spack built version of Seacas. This change correctly matches Seacas library names to CMake's version of Seacas's libraries and changes the path name to 'seacas' rather than 'sierra_seacas'
