x86/syscalls: Make __X32_SYSCALL_BIT be unsigned long
Currently, it's an int. This is bizarre. Fortunately, the code
using it still works: ~__X32_SYSCALL_BIT is also int, so, if nr is
unsigned long, then C kindly sign-extends the ~__X32_SYSCALL_BIT
part, and we actually get the desired value.
This is far more subtle than it deserves to be. Syscall numbers
are, for all practical purposes, unsigned long, so make
__X32_SYSCALL_BIT be unsigned long.
