scripts/sorttable: Use uint64_t for mcount sorting

The mcount sorting defines uint_t to uint64_t on 64bit architectures and
uint32_t on 32bit architectures. It can work with just using uint64_t as
that will hold the values of both, and they are not used to point into the
ELF file.

sizeof(uint_t) is used for defining the size of the mcount_loc section.
Instead of using a type, define long_size and use that instead. This will
allow the header code to be moved into the C file as generic functions and
not need to include sorttable.h twice, once for 64bit and once for 32bit.
