LOG: [z/OS][SystemZ] Clang dependency files are text files (#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.

Added:

    clang/tools/clang-scan-deps/ClangScanDeps.cpp

Removed:
