eal/x86: fix build sse3 functions with gcc < 4.4

In Suse11 SP3, there'll be errors for not found sse3 functions.
rte_memcpy.h: In function ‘rte_memcpy’:
rte_memcpy.h:625: error: implicit declaration of function ‘_mm_alignr_epi8’
rte_memcpy.h:625: error: nested extern declaration of ‘_mm_alignr_epi8’
rte_memcpy.h:625: error: incompatible type for argument 2 of ‘_mm_storeu_si128’

These functions defined in tmmintrin.h and should be included in.

Fixes: 9144d6bcdefd ("eal/x86: optimize memcpy for SSE and AVX")
