  [;SystemZ][z/OS] Fix llvm-ctxprof to open input files in text mode (#109691)

Reading text files on z/OS relies on auto conversion to handle
ASCII/EBCDIC correctly. For this to work files need to be opened in text
mode is that is the type of the file. This PR fixes `llvm-ctxprof`
utility in this regards which in turn fixes the following LIT failure on
z/OS:

`FAIL: LLVM :: Analysis/CtxProfAnalysis/flatten-zero-path.ll`
