jobby: no path to std_err for jobs in FRCE

the jobby short output file does not contain the correct path to the std error files for jobs on FRCE, but does work on biowulf

```
jobname state   std_err
cutadapt.sample=G2_Normal       COMPLETED       -
cutadapt.sample=G2_Tumor        COMPLETED       -
cutadapt.sample=G1_Tumor        COMPLETED       -
cutadapt.sample=G1_Normal       COMPLETED       -
```
