e29e30b139 [llvm-readobj] Change -long-option to --long-option in tests. NFC 
We use both -long-option and --long-option in tests. Switch to --long-option for consistency.

In the "llvm-readelf" mode, -long-option is discouraged as it conflicts with grouped short options and it is not accepted by GNU readelf.

While updating the tests, change llvm-readobj -s to llvm-readobj -S to reduce confusion ("s" is --section-headers in llvm-readobj but --symbols in llvm-readelf).

6e4dc6f23f [llvm-objcopy] Move elf-specific tests into subfolder 
In this diff the elf-specific tests are moved into the subfolder llvm-objcopy/ELF
(the change was discussed in the comments on https://reviews.llvm.org/D54674).
A separate code reivew wasn't sent for this change 
since Phabricator is failing to create such a large diff.

Test plan: 
make check-all
make check-llvm-tools
make check-llvm-tools-llvm-objcopy
