Move MPI support from flesh to a thorn

Move MPI support from flesh to thorn ExternalLibraries/MPI. This also
requires thorns that call MPI directly to declare this in their
configuration.ccl. Existing configurations using MPI need to include
ExternalLibraries/MPI into their thorn list.

* Declare that the flesh optionally uses MPI (because it needs to call
  MPI_Init)
* Update test case mechanism to find out whether MPI is used
* Handle configuration bindings for flesh
* Don't special-case Crays any more when configuring Linux
