[flang] Create a throwaway wrapper for the throwaway driver.

Add a script called flang to the bin directory that calls
f18 with the -I option pointing to the module files for the
predefined modules. The wrapper also sets the module suffix
to .fmf to avoid naming conflicts with module files generated
by other compilers. Now, the build creates and installs both
.mod and .fmf files for the predefined module files to
accommodate the flang script.
