perf session: Fix DEBUG=1 build with clang

The struct branch_stack->branch_stack.cycles field is a u64 :16
bitfield, and this somehow confuses clang 4.0 when checking the
arguments of a printf format, so cast the :16 to unsigned short to help
it.

Silences this:

  util/session.c:935:4: error: format specifies type 'unsigned short' but the argument has type 'u64' (aka 'unsigned long') [-Werror,-Wformat]
                          e->flags.cycles,
                          ^~~~~~~~~~~~~~~
