sysemu/tpm: Clean up global variable shadowing

Fix:

  softmmu/tpm.c:178:59: error: declaration shadows a variable in the global scope [-Werror,-Wshadow]
  int tpm_config_parse(QemuOptsList *opts_list, const char *optarg)
                                                            ^
  /Library/Developer/CommandLineTools/SDKs/MacOSX.sdk/usr/include/getopt.h:77:14: note: previous declaration is here
  extern char *optarg;                    /* getopt(3) external variables */
               ^
