s390/purgatory: Remove unused '-MD' and unnecessary '-c' flags
When clang's -Qunused-arguments is dropped from KBUILD_CPPFLAGS, it
warns while building objects in the purgatory folder:
clang-16: error: argument unused during compilation: '-MD' [-Werror,-Wunused-command-line-argument]
'-MMD' is always passed to the preprocessor via c_flags, even when
KBUILD_CFLAGS is overridden in a folder, so clang complains the addition
of '-MD' will be unused. Remove '-MD' to clear up this warning, as it is
unnecessary with '-MMD'.
Additionally, '-c' is also unnecessary, remove it while in the area.
