[Bug fortran/31587] Module files shouldn't be updated if their content doesn't change

An easy solution that I thought about implementing in the past would be to put
a checksum into the file header.  First the module file would be written to a
temporary file.  This file would be checksummed and only moved to the final
location if the checksum is different from that of the extant file.
