perf header: Fix build on old systems

For instance, on Fedora 8:

CC /home/acme/git/build/perf/util/header.o
cc1: warnings being treated as errors
util/header.c: In function ‘write_cpudesc’:
util/header.c:281: warning: implicit declaration of function ‘getline’
util/header.c:281: warning: nested extern declaration of ‘getline’
make: *** [/home/acme/git/build/perf/util/header.o] Error 1
make: Leaving directory `/home/acme/git/linux/tools/perf'
[acme@localhost linux]$

This happens due to header ordering, in perf util.h sets _GNU_SOURCE, so
it must come first.
