[PATCH] cpupower: remove stringop-truncation waring

[Anders Roxell]

The strncpy doesn't null terminate the string because the size is too
short by one byte.

parse.c: In function âprepare_default_configâ:
parse.c:148:2: warning: âstrncpyâ output truncated before terminating
    nul copying 8 bytes from a string of the same length
    [-Wstringop-truncation]
  strncpy(config->governor, "ondemand", 8);
  ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

Passing the length of the input argument to strncpy() is almost always
wrong and provides no extra benefit over strcpy(), and since 'ondemand'
fits within 15 bytes" and it null terminates the string its safe to use
strcpy().
