kconfig: revert change that was not needed for -Wformat-security

Recent GCC versions warn if the format string is not a literal
because the compiler cannot check the argument validity at compile
time.

Commit 192bc6948b02 ("Fix GCC format-security errors and convert
sprintfs.") blindly replaced sprintf() with strcpy(), including
many cases where the format parameter is a string literal.

For the kconfig change:

    sprintf(header, "   ");

..., here the format parameter is a string literal "   ", so it is
definitely equivalent to:

    strcpy(header, "   ");

Of course, if the 'header' did not have enough length for containing
"   ", it would be a security problem, but another problem.  (in this
case, the 'header' is 4 byte length buffer, so it is not a problem at
all.)

The kconfig code is kept as synced with Linux as possible, but this
change made the code out-of-sync for nothing.  Just reverting.
