- add a SUSE whitelist filtering out EICAR signatures (bsc#1246880)

- exclude pdfium-6425.tar.bz2 false positive. bsc#1239696

- disable EXCLUDELIST, upstream false positive was fixed. bsc#1222509

- EXCLUDELIST: Filter Python tarballs due to false positive
  (bsc#1222509) Win.Virus.Expiro-10026576-0

- revert EXCLUDELIST on qemu (FP is fixed - related to bsc#1199055)
- skip unpacking debuginfo/debugsource: sources are checked already
  and debuginfo contains no executable code
- use clamscan -r as it is faster than the xargs -P 0 execution (jsc#PED-3641)

- EXLUDELIST: Whitelist qemu binaries to avoid a FP (bsc#1199055)

- Allow using 1.5GB RAM per thread to avoid OOM conditions (bsc#1194857)

- Use short flags for cpio to support busybox cpio as well

- EXCLUDELIST: Removed lvm2 unit-test (bsc#1172626).

- and skip all the bells and whistles if we only have the
  busybox variants of xargs and grep (bsc#1183460)
