FindMPI: Restore MPI_<LANG>_COMPILE_FLAGS as a command-line string

Browse Source 
Refactoring in commit v3.10.0-rc1~103^2~2 (FindMPI: Modernization from
ground up, 2017-04-25) accidentally left this variable set as a copy of
the `;`-list in `MPI_<LANG>_COMPILE_OPTIONS`, but the flags variable is
documented as a command-line string.  Restore it now.

Fixes: #18349
