If target is bpf, there is no __loongarch__ definition, __BITS_PER_LONG
defaults to 32, __NR_nanosleep is not defined:

  #if defined(__ARCH_WANT_TIME32_SYSCALLS) || __BITS_PER_LONG != 32
  #define __NR_nanosleep 101
  __SC_3264(__NR_nanosleep, sys_nanosleep_time32, sys_nanosleep)
  #endif

Check __TARGET_ARCH_loongarch to include arch specified bitsperlong.h,
then __BITS_PER_LONG is 64, __NR_nanosleep can also be defined to fix
the following build errors:

  clang  -g -Werror -D__TARGET_ARCH_loongarch ... -target bpf -c progs/test_vmlinux.c ...
  progs/test_vmlinux.c:24:18: error: use of undeclared identifier '__NR_nanosleep'
