LOG: Open yaml, etc as text files (#199253)

These tests were failing on z/OS because the text input files were being
opened as binary.

```
FAIL: LLVM :: tools/dsymutil/AArch64/typedef-different-types.test
FAIL: LLVM :: tools/dsymutil/X86/mismatch.m
FAIL: LLVM :: tools/dsymutil/embed-resource.test
FAIL: LLVM :: tools/llvm-gsymutil/X86/elf-symtab-file.yaml
```
Open the files as text to solve the problems.
