Update get_sys_includes in Makefile with missing MIPS-related definitions
to fix many, many compilation errors building selftests/bpf. The following
added defines drive conditional logic in system headers for word-size and
endianness selection:

  MIPSEL, MIPSEB
  _MIPS_SZPTR
  _MIPS_SZLONG
  _MIPS_SIM, _ABIO32, _ABIN32, _ABI64
