Long output filename being truncated

[fischer-ncar]

Description of the issue:

Ran into an issue during testing where long output filenames for pop.dd, pop.do, pop.dt, and pop.dv are being
truncated.

There should be 0001-01-0000 at the end of the files.

These files are in

/glade/scratch/fischer/t/cesm2_3_alpha09c_alpha_intel/ERS_Vmct.f09_g17.1850_CAM60_CLM50%BGC-CROP_CICE5_POP2%ECO_MOSART_CISM2%GRIS-NOEVOLVE_WW3_BGC%BDRD.cheyenne_intel.allactive-defaultio.GC_D_c2_3_a09c_intel/run

So combine the filename and the directory, you get a string of 383 characters.

The command used to create the test is

./create_test ERS_Vmct.f09_g17.1850_CAM60_CLM50%BGC-CROP_CICE5_POP2%ECO_MOSART_CISM2%GRIS-NOEVOLVE_WW3_BGC%BDRD.cheyenne_intel.allactive-defaultio --test-root /glade/scratch/fischer/t/cesm2_3_alpha09c_alpha_intel/ --output-root /glade/scratch/fischer/t/cesm2_3_alpha09c_alpha_intel/ --test-id GC_D_c2_3_a09c_intel

Which is very similar to a prealpha test.
