[clang] [SystemZ][z/OS] Add text flag when parsing json (PR #211805)

[Abhina Sree via cfe-commits]

https://github.com/abhina-sree created https://github.com/llvm/llvm-project/pull/211805

This patch adds the text flag when we are opening json files to parse. 

This fixes the following two lit failures on z/OS

```
FAIL: Clang :: Analysis/Scalable/TypeConstrainedPointers/type-constrained-pointers.cpp
FAIL: Clang :: Analysis/Scalable/TypeConstrainedPointers/wpa-result-serialization.test
```
