Revisit legacy fastq file search code

[charles-cowart]

This is legacy code in FastQCJob and MultiQCJob:

https://github.com/charles-cowart/mg-scripts/blob/dd39ff0a1b59ecb6def1f0cd17194f32d783de60/sequence_processing_pipeline/FastQCJob.py#L85-L139

Look into possibly revising it using glob(), walk() or otherwise make it more compact.

Revisit other areas that involve zero_files directories and 'only-adapter-trimmed' as well.

Consider adding assumptions expressed in comments into the glob statement:
