Update WDLs to File inputs instead of Strings in ReadsQC

[samobermiller]

Updated:

• rqcfilter.wdl
• shortReadsqc.wdl
• sra2fastq.wdl

Removed:

• interleave_rqcfilter.wdl (no longer relevant)

Remaining:

• longReadsqc.wdl (still not hooked into automation, not a priority)

Direct tests (Nersc):

• 185860 (single accession) = passed
• 185861 (redirected noninterleaved) = failed (expected without redirect from automation)
• 186459 (direct version of noninterleaved) = passed
• 185862 (direct interleaved) = passed

Direct tests (Tahoma):

• 187135 (single accession) = passed
• 187136 (direct version of noninterleaved) = passed
• 187137 (direct interleaved) = passed
