build: Custom libmpi(_FOO) name option in configure

 * Add a configure environment variable to rename libmpi(_FOO).*
   - `OMPI_LIBMPI_NAME` defaults to `mpi`
 * This commit only impacts the installed libraries.
   Internal, temporary libraries have not been renamed to limit the
   scope of the patch to only what is needed.

For example:
```shell
shell$ ./configure OMPI_LIBMPI_NAME=wookie
...
shell$ find . -name "libmpi*"
shell$ find . -name "libwookie*"
./lib/libwookie.so.0.0.0
./lib/libwookie.so.0
./lib/libwookie.so
./lib/libwookie.la
./lib/libwookie_mpifh.so.0.0.0
./lib/libwookie_mpifh.so.0
./lib/libwookie_mpifh.so
./lib/libwookie_mpifh.la
./lib/libwookie_usempi.so.0.0.0
./lib/libwookie_usempi.so.0
./lib/libwookie_usempi.so
./lib/libwookie_usempi.la
shell$
```
