cpumf/lshwc: Fix compile errors due to use of non-standard __BITS_PER_LONG

Browse Source 
Use LONG_BIT provided by C standard in <limits.h>.

Fixes the following compile errors with buildroot:
lshwc.c: In function ‘parse_cpulist’:
lshwc.c:295:15: error: ‘__BITS_PER_LONG’ undeclared (first use in this function)
  295 |    no_a = i % __BITS_PER_LONG;
      |               ^~~~~~~~~~~~~~~

Fixes: 27a562da0a ("cpumf/lshwc: Program to extract complete counter sets")
