add asm/errno.h to linux/err.h (#8)

Browse Source 
Otherwise, we will have the following compilation error:

  /home/yhs/work/bcc-new/src/cc/libbpf/src/bpf_prog_linfo.c:
      In function ‘dissect_jited_func’:
  /home/yhs/work/bcc-new/src/cc/libbpf/src/bpf_prog_linfo.c:88:10:
      error: ‘EINVAL’ undeclared (first use in this function)
    return -EINVAL;

The original linux/err.h at linux:tools/include directory
does include "asm/errno.h" as well.
