perf tools: Fix build against newer glibc
Upstream glibc commit 295e904 added a definition for __attribute_const__
to cdefs.h. This causes the following error when building perf:
util/include/linux/compiler.h:8:0: error: "__attribute_const__"
redefined [-Werror] /usr/include/sys/cdefs.h:226:0: note: this is the
location of the previous definition
Wrap __attribute_const__ in #ifndef as we do for __always_inline.
