[PATCH] hash: fix build error due to missing include

[Bruce Richardson <bruce.richardson@intel.com>]

The file "rte_thash.c" uses the rte_cpu_get_flag_enabled() API but does
not include "rte_cpuflags.h". Add the include to fix build issues this
causes:

../lib/hash/rte_thash.c: In function ‘rte_thash_gfni_supported’:
../lib/hash/rte_thash.c:79:13: error: implicit declaration of function
‘rte_cpu_get_flag_enabled’ [-Wimplicit-function-declaration]
   79 |         if (rte_cpu_get_flag_enabled(RTE_CPUFLAG_GFNI) &&
         |             ^~~~~~~~~~~~~~~~~~~~~~~~

Fixes: d8f0f514428e ("eal/x86: remove useless include from spinlock header")
