Expand build matrix to test install.sh

 An additional Mac OS X and Linux case is added to use install.sh to
 perform the installation. GCC cannot be built from source because
 Travis-CI will time out, but it may be possible to build CMake, MPICH
 and any other dependencies that are missing.

 Due to the fact that the install script is rather verbose, and logs
 longer than 4 MB are assumed to be erroring, the output of
 `install.sh` is written to a file, and a status message is printed
 every 5 minutes while install.sh is running. Upon success and
 failure, install.log is printed to stdout. One might have to
 "download log" due to truncation to view this.
