perf jitdump: Add the right header to get the major()/minor() definitions

Noticed on Fedora Rawhide:

  $ gcc --version
  gcc (GCC) 6.1.1 20160721 (Red Hat 6.1.1-4)
  $ rpm -q glibc
  glibc-2.24.90-1.fc26.x86_64
  $

    CC       /tmp/build/perf/util/jitdump.o
  util/jitdump.c: In function 'jit_repipe_code_load':
  util/jitdump.c:428:2: error: '__major_from_sys_types' is deprecated:
    In the GNU C Library, `major' is defined by <sys/sysmacros.h>.
    For historical compatibility, it is currently defined by
    <sys/types.h> as well, but we plan to remove this soon.
    To use `major', include <sys/sysmacros.h> directly.
    If you did not intend to use a system-defined macro `major',
    you should #undef it after including <sys/types.h>.
    [-Werror=deprecated-declarations]
    event->mmap2.maj   = major(st.st_dev);

Fix it following that recomendation.
