FUNITCTSM tests fail on Izumi due to a ccs_config update

### Brief summary of bug

With ESCOMP/CTSM#3125, the FUNITCTSM tests fail on Izumi due to an update for ccs_config in ccs_config_cesm1.0.42

### General bug information

**CTSM version you are using:** ctsm5.3.045-181-g54e640b6

**Does this bug cause significantly incorrect results in the model's science?** [Yes / No]

**Configurations affected:** Just the PF unit testing and only on Izumi

### Details of bug

FUNITCTSM_P1x1.f10_f10_mg37.I2000Clm50Sp.izumi_intel

fails at build time (as well as when run by hand under the src directory).

This starts with ccs_config_cesm1.0.42
