perf hist: Fix missing getline declaration

hist.c needs to include util.h so that it gets stdio.h
inclusion with __GNU_SOURCE defined.

Fixes:
	util/hist.c: In function ‘hist_entry__parse_objdump_line’:
	util/hist.c:931: erreur: implicit declaration of function ‘getline’
	util/hist.c:931: erreur: nested extern declaration of ‘getline’
