package/cpulimit: correct function signature to use named parmeters

Update 0005-Correct-loop-function-signature.patch to include a named
parameter otherwise the following compiler warning turned error is
triggered:

busy.c:6:1: error: parameter name omitted
 void *loop(void *)
 ^~~~

Interestingly, this builds with GCC > 10.x, but fails fails with GCC
<= 10.
