ForUTF unittests

The following Fortran modules still miss testing:

• mo_hash_table
• mo_io_units
• mo_namelist
• mo_simple_dump
• mo_util_file (tested on C/C++ side)
• mo_util_libc
• mo_util_nml
• mo_util_rusage
• mo_utile_stride
• mo_util_string !63 (merged)
• mo_util_system
• mo_util_timer (testing incomplete)

added test label

mo_util_file creates link for files and checks file sizes. I have written some tests with googletest and I don't think FortUTF can do anything here. You can remove it from the list.

marked the checklist item mo_util_file as completed

Once either !21 (closed) or !23 (closed) is merged, it would be great to make the Fortran unit tests pass with the NAG compiler. Most probably, it will require a PR to the ForUTF repo. Thanks!
