LOG: [clang][test] Avoid writing to a potentially write-protected dir (#96457)

The test clang/test/Preprocessor/embed_weird.cpp creates a file directly
in the Inputs dir in the llvm-project repo instead of the temporary
directory. The llvm-project repo may be write protected e.g. in a
sandboxed environment.

This patch creates a separate temporary directory where the
null_byte.bin file is created along with the rest of copies of the other
embed-files needed for the testcase.
