[PATCH xserver 3/3] test: Fix sizeof expression.

[msrb at suse.com]

From: Michal Srb <msrb at suse.com>

Instead of getting (sizeof(char[10]) - 1) = 9 it was getting sizeof(char*) = 8. Not that it changes much.

simple-xinit.c:90:65: warning: sizeof on pointer operation will return size of 'char *' instead of 'char [10]' [-Wsizeof-array-decay]
    ret = read(displayfd, display_string, sizeof(display_string - 1));
                                                 ~~~~~~~~~~~~~~ ^
