[clang] [z/OS][SystemZ] Clang dependency files are text files (PR #121849)

[Kai Nacke via cfe-commits]

https://github.com/redstar created https://github.com/llvm/llvm-project/pull/121849

The dependency file and the P1689 file are text files, but the
open call misses the OF_Text flag. This PR adds the flag.
Fixes regressions in test cases ClangScanDeps/modules-extern-unrelated.m
and ClangScanDeps/P1689.cppm.
