Merge branch 'veristat-files-list-txt-notation-for-object-files-list'

Eduard Zingerman says:

====================
veristat: @files-list.txt notation for object files list

A few small veristat improvements:
- It is possible to hit command line parameters number limit,
  e.g. when running veristat for all object files generated for
  test_progs. This patch-set adds an option to read objects files list
  from a file.
- Correct usage of strerror() function.
- Avoid printing log lines to CSV output.

Changelog:
- v1 -> v2:
  - replace strerror(errno) with strerror(-err) in patch #2 (Andrii)

v1: https://lore.kernel.org/bpf/3ee39a16-bc54-4820-984a-0add2b5b5f86@gmail.com/T/
